1686. In addition to the central manor house, separate outbuildings for baking and brewing, a large stable, boathouse, and numerous farm buildings were erected. Penn's plan was to establish the sort of gentleman's country estate similar to his home in England. Penn spent most of his time in the soon-to-be capital city of Philadelphia governing his settlement, leaving the manor house empty for long periods of time. From 1699 to 1701, he rented "The Slate Roof House" in Philadelphia as his second residence and city townhouse. He left the colony for England in 1701 to fend off a threatening French claim to his British grant, dying destitute in his home town or Ruscombe after having been defrauded by his English agent of rents and income due him. By 1736, one of Penn's sons remarked that the Pennsbury house "was very near falling, the roof open as well as the windows and the woodwork almost rotten." It remained in family hands until 1792. At some time before 1820 a farmhouse today known as the Crozier House was built over part of the original Pennsbury foundations. It still stands on the larger property but was moved. The Warner Company of Philadelphia, established in 1794 as a dealer in sand, gravel and other construction materials, acquired much of the otherwise deserted land where the manor once stood. In 1932, on the 250th anniversary of Penn's arrival, the company donated some of the lands to the Commonwealth of Pennsylvania. Charles Warner, its president, presented the deed for a just under ten-acre parcel where the Pennsbury buildings had stood to the state as a permanent memorial to Penn. The Pennsylvania Historical Commission was given responsibility for what was then known as The Pennsbury Memorial. Site discovery and reconstruction In the 1920s and 1930s there was considerable interest in preserving buildings and history of colonial America, due in part to the country's celebration of its sesquicentennial and the stresses of waves of immigration, a world war, and the Great Depression. Sites relating to Founding Fathers were reconstructed in this era, notably Abraham Lincoln's former home in New Salem, Illinois, in the 1920s and the long-destroyed northern Virginia birthplace of George Washington, Wakefield, in 1930." Also in Virginia the Rockefeller family supported the restoration and reconstruction of Colonial Williamsburg. At that time, the commission, Commonwealth, and other sources collaborated to construct a colonial revival manor house and
