Garden Design - Walls & Fences around The White House in Early America

Watercolor of the White House's South Grounds, 1827. This watercolor painted by an anonymous artist, depicts the White House and its grounds from the southwest. The watercolor shows the recently built South Portico, constructed in 1824 during the Monroe administration, Thomas Jefferson’s stone walls, workers’ cottages, an orchard, & President John Quincy Adam's tree nursery.

To expand the grounds around the proposed White House, Washington purchased the land for what is now the South lawn from a tobacco planter named Davy Burns, while the North grounds originally belonged to the Pierce family before falling into the hands of speculators.

1803 White House by Nicholas King in the Huntington Library, San Marino, California. The cornerstone of the President’s House was laid October 13, 1792. When the White House was first occupied in 1800, the site of the South Lawn was an open meadow gradually descending to a large marsh, the Tiber Creek, & to the Potomac River beyond.

The gardens & grounds at the White House evolved slowly as the nation grew. Initially President George Washington (1789–1797) chose French engineer & architect Pierre-Charles L'Enfant (1754-1825) to draw a plan of the city of Washington, envisioning a setting of terraced formal gardens descending to Tiber Creek.

When Washington & L'Enfant mapped out the "President's Park," in 1791, Washington sketched reflecting pools & terraced gardens falling toward the water from an executive palace rivaling Versailles on 82 acres. When finally completed, the White House was about a quarter of the size L'Enfant dreamed of, but gardens would surround the residence.

After Washington dismissed L’Enfant, the design of the White House was thrown open to an architectural competition in 1792. James Hoban (1758–1831), an Irish-born & trained architect then living in Charleston, South Carolina, won the design competition for the White House. Hoban immigrated to the United States working as an architect & builder in Philadelphia & Charleston, from 1785 until his move to the nation’s capital in 1792.

When John Adams (1797–1801), the 1st President to live in Hoban's proposed mansion, moved into the house in 1800, one Washingtonian wrote that the grounds were "at present in great confusion, having on it old brick kilns, pits to contain water used by the brick makers."

Benjamin Latrobe (1764-1820) noted in 1803, "The surrounding Ground was chiefly used for Brick yards, it was enclosed in a rough post and rail fence." Presidents were faced with a scraggly, unpromising vista of tobacco-depleted clay soil scattered with abandoned workers' cottages bordered by a malarial swamp. The greatest majority of presidential landscaping efforts would be consumed with grading & filling projects throughout the 19C.

In 1801, President Thomas Jefferson (1801-09) began planning improvements for the White House gardens & grounds, including a stone wall around the house. President Thomas Jefferson ordered the construction of a wooden post & rail fence around the White House. By 1808, he had replaced the fence with a stone wall that enclosed the White House Grounds. At the south end of the grounds, a ha-ha wall (a sunken wall that serves as a vertical barrier while providing an uninterrupted view of the landscape) stood to prevent livestock from grazing in the garden. President Jefferson envisioned the South Grounds as a private garden with serpentine walks & a lawn that extended down to Tiber Creek (which runs under present-day Constitution Avenue), edged by a flower border. The North Grounds were to be formal, symmetrical, & open to the public.

Jefferson, who was always arranging & rearranging the grounds at Monticello, was the first president to devise an overall landscape plan for the grounds. The plan included the fence, as well as grading & planting the south grounds for more privacy.

We learn from Margaret Bayard Smith's diary, published in 1906, the Jefferson "was very anxious to improve the ground around the President's House; but as Congress would make no appropriation for this and similar objects, he was obliged to abandon the idea, and content himself with enclosing it with a common stone wall and sewing it down in grass. Afterwards when the Grisly Bears, brought by Capt Lewis from the far west, (where he had been to explore the course of the Missouri,) were confined within this enclosure, a witty federalist called it the President's bear-garden."

Jefferson wanted groves of trees, and he picked the location for the flower garden. Fences & walls were eventually built, where he had specified. He also directed the planting of numerous trees between 1802 -1806.  Smith wrote that "Jefferson's design to have planted them exclusively with trees, shrubs and flowers indigenous to our native soil. He had a long list made out in which they were arranged according to their forms and colors and the seasons in which they flourished. To him it would have been a high gratification to have improved and ornamented our infant City. But the only thing he could effect, was planting Pennsylvania Avenue with Lombard Poplars, which he designed only for a temporary shade, until Willow oaks, (a favorite tree of his) could attain a sufficient size. But this plan had to be relinquished as well as many others from the want of funds."

Jefferson completed grading of the South Lawn, building up mounds on either side of a central lawn, similar to the 100-foot diameter mounds he built at his villa retreat Poplar Forest for his retirement in 1809.

President Jefferson & his surveyor of public buildings, Benjamin Latrobe located a triumphal arch as a main entry point to the grounds, just southeast of the White House. Jefferson's arc of triumph was flanked by two memorial weeping willow trees. “No occupation is so delightful to me as the culture of the earth...but though an old man, I am but a young gardener," he wrote to a friend from his Poplar Forest retreat in 1811.

William Stebbins described the grounds around the White House in Washington D. C. in 1810, "Extended my walk alone to the President's house: -- a handsome edifice, tho' like the capitol of free stone: the south yard principally made ground, bank'd up by a common stone wall: a plain picket fence on each side, the passage way to the house on the north: --some of the pickets lying on the ground."

Hostilities with Great Britain, begun in 1812, culminated in the invasion of Washington on August 24, 1814. British troops entered the defenseless city; ate a dinner prepared for the fleeing President at the White House; and then torched the building, destroying all but the outer walls and most of the plantings.

Paul Jennings, President James Madison's (1809–1817) personal slave who witnessed the burning, reports that it was the Madison's White House gardener, and not Dolley Madison who saved the portrait of George Washington from burning with the White House. "When the British did arrive, they ate up the very dinner, and drank the wines, &c., that I had prepared for the President's party."

At the urging of James Madison, Congress decided to rebuild rather than move the capital to another city. Hoban returned to reconstruct the President’s House, as it had been before the fire. President James Monroe (1817–1825) moved into a new house in the autumn of 1817.  A new semicircular driveway marked by eight stone piers, an iron fence & gates was built across the North Front of the White House.

While the White House was being rebuilt after the 1814 fire, James Monroe increased tree plantings on the grounds based on plans by architect Charles Bulfinch.

The front of the White House was used as a common for fairs & parades until 1822, when Pennsylvania the avenue was cut through the north side of the President’s Park & soon after a public park was established.

The federal government used Charles Bulfinch’s (1763–1844) planting scheme for a thick grove of trees for the square north of the White House & named the park in honor of General Lafayette in 1824-1825.

1833 The White House

A long & heavy wrought iron fence was installed along Pennsylvania Avenue on the north side of the White House. Jefferson’s stone wall was cut down along this run & served as the foundation for the new fence. This work was integrated into the existing 1818-1819 semicircular fencing.

During the 1830's President Andrew Jackson (1829–1837) became a big supporter of the White House gardens hiring several laborers to assist White House gardener John Ousley. During Jackson's term elm, maple, & sycamore trees were planted for the first time. He had walks laid out among garden beds filled with foxglove, dragonhead, sweet William and daisies.

Jefferson’s stone wall was cut down along this run & served as the foundation for the new fence. This work was integrated into the existing 1818-1819 semicircular fencing.

The famous Jackson magnolias were added to the White House grounds in 1835, which he planted in honor of his wife Rachel, who died shortly before he took office in 1829. The oldest surviving trees on the property now are those two southern magnolias (Magnolia grandiflora) at the east end of what is now the Rose Garden.
About this time, square & rectangular garden beds were no longer in fashion. They could be oval, circle, diamond, star, crescent, or any shape other than a rectangle or square. Walls still remained.

Politics invaded the garden during Martin Van Buren's term from 1837 to 1841. Leafing through White House bills, Rep. Charles Ogle of Pennsylvania declared that Van Buren had been busy "constructing fountains, paving footways, planting, transplanting, pruning and dressing horse chestnuts, lindens, beds and borders, training and irrigating honey suckles, trumpet creepers, primroses, lady slippers...and preparing beautiful bouquets for the palace saloons."

In 1873, President Ulysses S. Grant expanded the grounds southward & enclosed them with iron fencing. He also began the policy of closing the grounds at sunset but successive presidents determined their own policy upon taking up residency at the White House. 

From its start as a wooden post & rail fence in 1801, the walls & fences around the White House have evolved with the changing landscape of the city of Washington & the security needs of the First Family. In 1893, Grover Cleveland closed the South Grounds after strangers attempted to take photographs with his youngest daughter Esther. In 1901, Theodore Roosevelt briefly reopened the South Grounds, but visitors continued to take liberties with access & tried to photograph & meet with the Roosevelt family, forcing the president to close the South Grounds. In 1913, William Howard Taft restricted access to the North Grounds, only permitting the public to enter on certain days & specific times.

Garden Design - Walls at Public Buildings in Early America

State House Garden in Philadelphia. Jedidiah Morse 1789, describing the State House Yard in Philadelphia noted that “The state house yard, is a neat, elegant & spacious public walk, ornamented with rows of trees; but a high brick wall, which encloses it, limits the prospect.”

Brick & stone walls were usually enclosed the grounds of public buildings & grave-yards in early America. Most private homes & gardens were "well paled in" with fences made of wood. An act of the Virginia General Assembly of 1705, intended to protect the gardens from stray pigs, horses & cattle, required the owners of every lot on Duke of Gloucester Street in Williamsburg, to "inclose the said lots, or half acres, with a wall, pales, or post and rails, within six months after the building, which the law requires to be erected thereupon, shall be finished."  The minimum height of the fence was set at 4 & one-half feet & but many were built higher. 

Early colleges in America often had walled grounds. My absolute favorite description of one of these walls was by Moreau de St. Mery (1750-1819), when he visited Princeton, New Jersey in the 1790s.

College at Princeton, New Jersey in 1764 "The central part of the facade protrudes. There are ten windows on each side of it, and below the pediment there are six other windows on the facade. All in all, this building has an impressive appearance for America...Before it is a huge front yard set off from the street by a brick wall, and at intervals along the wall are pilasters supporting wooden urns painted gray. This front yard is untidy, covered with the droppings of animals who come there to graze...In its center is an old iron cannon, a four-pounder, without a carriage. This cannon, the dilapidated condition of the encircling wall, the number of decorative urns that have fallen to the ground, everything bears the imprint of negligence, and one reaches the building grieved that the pupils have such an unpleasant example before their eyes." (Moreau de St. Mery on Princeton)" 

On May 8, 1704, describing in the Journals of the House of Burgesses of Virginia the construction in Williamsburg, Virginia, “Ordered. That the consideration of the proposall of the said Committee relating, to the Capitol being inclosed with a brick wall be referred til tomorrow morning. Ordered. That the Overseer appointed to inspect and oversee the building of the Capitol make a Computation what the Charges may amount to of inclosing the Capitol with a Brick Wall of two Bricks thick and four feet and a half high to be distant sixty foot from the fronts of the East and West Building and the said building and that he lay the same before the House to morrow.”

Pennsylvania Hospital, Eighth & Pine streets. Founded in 1751 as the first hospital in the Colonies, it also became the first place to provide clinical instruction to medical students in what would become the United States. (As of 1767, requirements for a Penn medical degree included one year attending the practice of the hospital. Students purchased tickets for hospital privileges, which included use of the library.) The public grounds of the Philadelphia Hospital, where patients & their families could find a few moments away from their cares, were also enclosed by a brick wall.

Peter Kalm wrote of New York City, "In addition to the hospital...there is another farther up Broadway... There is a yard where patients are allowed to walk, and plans call for planting trees in it." The hospital in Philadelphia also had a walled yard planted with trees and crossed with walks for its patients and their visitors to walk in.

In 1706, the act of the Virginia legislature authorizing the building of the Governor's Palace allocated 635 pounds for the construction of the garden with these instructions, "that a Court-Yard, of dimensions proportionable to the said house, be laid out, levelled and encompassed with a brick wall 4 feet high with the balustrades of wood thereupon, on the said land, and that a Garden of the length of 254 foot and the breadth of 144 foot from out to out, adjoining to the said house, to be laid out and levelled and enclosed with a brick wall, 4 feet high, with ballsutrades of wood upon the said wall, and that handsome gates be made to the said court-yard and garden."

My favorite depiction of walls in the Middle Plantation, Williamsburg's early name, is from a 1702 drawing by a Swiss traveler Franz Ludwig Michel which depicts the brick walls at both the 1699 Capitol and the 1680 Bruton Parish Church. (Some of my way-back relatives are buried in that walled churchyard.) I know these aren't garden walls, but there is an antique peace that envelopes that graveyard.

There is some evidence that the walled gardens at both the Governor's Palace and the College of William and Mary were plotted by English garden designer George London, who was working on Hampton Court under architect Christopher Wren during the same period. London was building brick walls around gardens there as well.

In a letter from English garden writer John Evelyn (1620-1706) to Virginia planter John Walker, Evelyn wrote in 1694, "Mr. London (his Majs Gardner here) who has an ingenious Servant of his, in Virginia, not unknown to you by this time; being sent thither on purpose to make and plant the Garden, designed for the new College, newly built in yr Country."

Williamsburg Brick Wall

In 1706, the act of the Virginia legislature authorizing the building of the Governor's Palace allocated 635 pounds for the construction of the garden with these instructions, "that a Court-Yard, of dimensions proportionable to the said house, be laid out, levelled and encompassed with a brick wall 4 feet high with the balustrades of wood thereupon, on the said land, and that a Garden of the length of 254 foot and the breadth of 144 foot from out to out, adjoining to the said house, to be laid out and levelled and enclosed with a brick wall, 4 feet high, with ballsutrades of wood upon the said wall, and that handsome gates be made to the said court-yard and garden."

Further authorizations for money to construct the garden were made in 1710. The garden authorized in 1706 was not complete until 1720. When new Virginia Governor William Gooch (1681-1751) arrived in 1727, he wrote of a "handsome garden, an orchard full of fruit, and a very large park."

Brick Wall Around Governor's Palace in Williamsburg, Virginia.

The entrance courtyard was separated from the rear formal garden by brick walls. A gate in the brick wall of the formal garden to the east led to Lieutenant Governor Alexander Spotswood's (1676-1740) "falling garden," a series of 3 terraces descending to a ravine where Spotswood had a stream dammed to create a "fine canal." 

While the Palace's formal gardens & protective brick walls reflected the Baroque style, which had been popular for years since Le Notre's Versailles, opening the gate in the brick wall & stepping out into the countryside to a natural ravine with its canal was an anticipation of the freedom of the picturesque jardin anglais just over the horizon.

Even Williamsburg's Powder Magazine, built in 1714, had an octagonal 10' high brick wall constructed around it in 1755, leaving a 20' wide green courtyard surrounding the building.

Hugh Jones (1669-1760) descibed the William and Mary College garden about 1716, "It is approached by a good Walk, and a grand Entrance by steps with good Courts and Gardens about it."

An onlooker noted in the Maryland Gazette on  January 4, 1770, describing the State House, “The General Assembly having been pleased to grant to the Value of 7500 Sterling, for building a State-House. . . & for enlarging, repairing, & enclosing the Parade, not exceeding its present Length of 245 feet, & 160 in Breadth, designed to be enclosed with Stone or Brick Wall, & Iron Palisadoes, if the Iron Inclosure should not exceed 500 Sterling.”

Joseph Scott, 1806, describing a public prison in Philadelphia, PA . “The yard belonging to the criminal prison extends nearly to Prune street, on which is the debtors’ apartment. The whole is surrounded by a lofty stone wall.”

In 1811, David Hosack, noted the establishment of the Elgin Botanic Garden, New York, NY 

“Accordingly, in the following year, 1801, I purchased of the corporation of the city of New York twenty acres of ground...At a considerable expense, the establishment was inclosed by a well constructed stone wall...The whole establishment was enclosed by a stone wall, two & an half feet in breadth, & seven & an half feet high.”

Garden Design - Walls & Fences & Symbolism at the US Capitol in Early America

Cherry Blossoms at the United States Capitol Building. 

The 1863 Statue of Freedom on the Capitol dome which features a woman in a robe & headdress holding a sword in one hand & a laurel wreath of victory in the other, was designed by Thomas Crawford. The 19.5-foot statue weighs about 15,000 pounds.

In 1789, the US Congress - Senate & House of Representatives - assembled for the 1st time in New York. 

Amos Doolittle. View of the Federal Edifice in New York. The Columbian Magazine Philadelphia, August 1789. 

Congress moved to Philadelphia in 1790, and then to Washington, DC, in 1800. In May 3, 1802, Washington DC was incorporated as a city. In 1807, the Congress moved into the U.S. Capitol in Washington, DC, 4 years before the Capitol’s House wing was fully completed. 

In 1814, invading British forces burned the Capitol. It would be another 5 years before the chambers were fully restored. The Old Hall of the House, where Congress met from 1819 to 1857, was redesigned by Benjamin Henry Latrobe after the 1st hall was destroyed in the fire set by British troops in 1814. In 1857, the House met for the first time in its present-day chambers. 

This posting will look at the development & the symbolism of the building & the grounds around the United States Capitol, and how those considerations determined that there would be few fences or walls at the Capitol. 

The Library of Congress tells us that symbols are history encoded in visual shorthand. Eighteenth century Euro-Americans invented or adopted emblems - images accompanied by a motto &  personifications & allegorical figures - to express their social & political needs. They used them as propaganda tools to draw together the country's diverse peoples (who spoke many languages) in order to promote national political union, hoping to secure liberty & equal justice for all.

Classical Temple Dedicated to Liberty, Justice, and Peace. James Trenchard. Temple of Liberty. The Columbian Magazine, (Philadelphia) 1788, Library of Congress.  In 1788, Philadelphia's Columbian Magazine published this engraving. The artist Trenchard, born in 1746, at Penns Neck in Salem County, New Jersey, was an engraver & seal cutter in Philadelphia, and the artist for many of the plates appearing in the Columbian Magazine, whose circulation was the largest of any 18C magazine published in America.

This engraving of a classical temple building depicts statues on the roof, including Libertas (liberty), Justicia or Themis (justice), & Ceres (peace). Libertas is at the peak with the others on the corners. In the background a rising sun radiating beams of light with one shining upon Libertas holding her staff & freedom cap. Emerging from the pure, bright sunlight in the distance is the new nation--lady Columbia with an eagle headdress. Standing below is Concordia holding a horn of plenty; Columbia's winged son holding a scroll with CONSTITUTION written on it; and Clio, the muse of history, beginning to write the history of the new nation. Scrolling across the front of the classical temple are the words: SACRED TO LIBERTY, JUSTICE AND PEACE. Below this engraving was written,

Behold a Fabric now to Freedom rear'd,
Approved by friends, and ev'n Foes rever'd,
Where Justice, too, and Peace, by us ador'd,
Shall heal each Wrong, and keep ensheath'd the Sword
Approach then, Concord, fair Columbia's Son,
And faithful Clio, write that "We Are One."

The agreement on the general plan for the nation's capitol called for a 100-square mile federal district to be located somewhere along the Potomac River at a site to be chosen by fellow river-property owner, George Washington. Washington picked the junction of the Potomac & Anacostia Rivers. He then chose Pierre Charles L'Enfant, a military artist who had served under him at Valley Forge, to design the new federal city.

The land on which the Capitol stands was 1st occupied by the Manahoacs & the Monacans, who were subtribes of the Algonquin Indians. Early settlers reported that these tribes occasionally held councils not far from the foot of the hill. This land eventually became a part of Cerne Abbey Manor. At the time of its acquisition by the federal government "Jenkins Hill" was owned by the well-to-do Marylander Daniel Carroll of Duddington, and it stood on a tract of land originally known by the more classically-inspired name of "New Troy."

Construction proceeded slowly under a succession of architects, including Stephen Hallet (1793), George Hadfield (1795-98) and James Hoban (1798-1802), architect of the White House, who completed the Senate wing in 1800. Though the building was incomplete, the Capitol held its first session of United States Congress on November 17, 1800. 

The city's supporters, like L'Enfant & Washington, expected that the capital would grow to the east, leaving the Capitol & the White House essentially on its outskirts. For some years the land around the Capitol was regarded as a common, crossed by roads in several directions & intended to be left as an open area.

By 1837, the Washington Guide reported, The Capitol Square has been enlarged to the west, by taking in that part of the Mall extending from the circular road to First street, west; making about eight acres additional. This space has been properly graded and planted with trees and shrubs by Mr. James Maher, the public gardener:—the other part of the square was planted by the late John Foy, a man of excellent talents and taste. A good substantial stone wall, surmounted by an iron-railing, surrounds the whole square. When the walks are completed, and the water-fountains arranged, this square will afford the most beautiful and healthful walks: a subject well deserving public attention.

Boston architect Charles Bullfinch supervised the development of the building & grounds in 1818; and completed the building, with only slight modifications of Benjamin Latrobe's master plan, in 1830. Under Bullfinch in 1825, a plan was devised for imposing order on the Capitol grounds, & it was carried out for almost 15 years. The plan divided the area into flat, rectangular grassy areas bordered by trees, flower beds, & gravel walks. The growth of the trees, however, soon deprived the other plantings of nourishment, & the design became increasingly difficult to maintain in light of sporadic & small appropriations.

In 1874, Congress passed an act making Frederick Law Olmsted (1822-1903) the first landscape architect of the United States Capitol. Olmsted accepted the job, wishing to "train the tastes of the nation." The mid-19th-century enlargement of the US Capitol, in which the House & Senate wings & the new dome were added, required that the Capitol grounds be expanded.

John Singer Sargent (American artist, 1856-1925) Frederick Law Olmsted 1895

For the seat of the legislative branch of the United States of America, Olmsted wanted to make the Capitol building the crowning centerpiece. Olmsted was determined that the grounds should complement the building. 

His 15-year-long project on the grounds of the United States Capitol did envision an open setting immediately surrounding the Capitol & a more naturalistic scenery with shrubbery & trees further from the Capitol, nearer to its entrances.  Because of the many streets & entrances merging at the capitol, the creation of a workable circulation system dominated the design process. The east side of the Capitol needed more open spaces for large masses of people gathered for inaugurations & other large events normally held at the East Front. Two large naturalistic ovals with scattered trees were designed for the east side to accommodate the grounds needed during such events.

Olmsted's 1874 Plan for the US Capitol.  Olmsted wrote in 1874: "…. The elements of the plan must be as few, large and simple as they well can be consistently with convenience." He further describes, "two elliptical plots of ground will then be left, unbroken by roads, each 500' in length and 400' in breadth. They will have a gently undulating surface, will be partially shaded by a few groups of large trees between which the eye will range over glades of turf."

By 1879, the roads were paved & most of the work on the east side of the grounds was completed. The stone walls on the west side of the grounds were almost finished.
