Wilderness Landscape & Natural Heritage
Graeme Park is located in Horsham, Pennsylvania, and preserves the Keith House, the only remaining colonial mansion in Pennsylvania open to the public. Set on approximately 42 acres, the site reflects the lifestyle and architectural style of the mid-1700s. The Keith House was built by William Keith, a colonial governor, and later owned by Colonel Henry Graeme, whose family legacy the park honors. The property features formal gardens, open meadows, wooded areas, and a walking trail that connects visitors with the surrounding natural environment. The site offers guided tours of the manor, providing historical context about colonial Pennsylvania, early American politics, and the Graeme family's role in the region’s development. Visitors can explore seasonal events, educational programs, and re-enactments that highlight colonial-era life. The park’s landscape includes native tree species and serves as habitat for local wildlife, supporting passive recreation such as bird watching and nature walks. Graeme Park appeals to history enthusiasts, families, and outdoor lovers seeking a quiet setting with significant cultural value close to the Philadelphia metropolitan area.
