Baltimore Country Seat Druid Hill by Francis Guy
Because Druid Hill did not sit directly on the harbor basin in Baltimore, an artificial lake was built on the grounds. Gentry sometimes created a man-made body of water in their pleasure grounds near their dwelling affording recreation, food, ice, and beauty.
In 1806, Rosalie Steir Calvert wrote to her father in Europe from her estate Riversdale in Prince George's County, Maryland. She had been consulting with architect artist William Birch about the design of their grounds.
Birch drew us a plan for the grounds. He thinks an artificial lake would be better on the south of the house than on the north, since the terrain is better adapted and it would be easier to make there.
Two years later she wrote to her father, Lake just finished, which looks like a large river on the southern side, gives a very beautiful effect and furnishes us at the same time with fish and ice for our ice-house.
