The main house of the farmstead, built in 1758, is Georgian style architecture with additional features reflecting the Germanic background of its builder, Peter Wentz. The Wentz Farmstead is surrounded by 90 plus acres managed as an eighteenth century working farmstead. With its strategic location to Philadelphia
during the American Revolution, General George Washington chose the farmstead for his headquarters. At the Wentz Farmstead, Washington planned the Battle of Germantown, which took place October 4, 1777. It was here on October 18, 1777 that the news of Burgoynes surrender to General Gates at Saratoga was received and celebrated. A reconstructed barn houses farm animals that are typical of the period. There are gardens, orchards and fields cultivated as they would have been in the period. There is also an active period crafts program. Various informational programs, events and demonstrations are presented year round at the Farmstead.
