The mansion house at Graeme Park-a rare surviving example of early colonial American architecture-was conceived of as a utilitarian structure on a Governor's plantation, the structure became the Georgian-styled centerpiece of a country retreat and backdrop for an intellectual salon that largely concentrated on the development of genteel republican ideologies. Graeme Park, originally called Fountain Low, rose on an improved portion of Lieutenant Governor Sir William Keith's 1,735 acre Pennsylvania plantation. The three-story structure was built in 1722 probably envisioned as a malt-house for the production of alcohol. In 1739, the plantation was purchased by Dr. Thomas Graeme, the son-in-law of Keith, and renovated during his ownership into a high-style Georgian summer dwelling for himself and his family, which in the mid-1760s became their year-round residence... -- Historic American Buildings Survey (HABS PA-579)
