Horsham Preservation and Historical Association

HPHA is extremely sad to report the passing of our dear friend Peter Choate.

The Horsham Preservation & Historical Association (HPHA) is is a community benefit organization based in Horsham Township, Montgomery County, Pennsylvania, USA dedicated to identifying, studying, preserving and protecting the historical heritage, buildings and artifacts of our area.

Located in southeastern PA, just north of Philadelphia, Horsham is in an area rich in history going back to our colonial period. The Governor Sir William Keith House/Graeme Park (National Historic Site), the Horsham Friends Meeting House (National Historic Site), the c 1735 Kenderdine Mill, and, the c1721 Penrose-Strawbridge House (currently under restoration by HPHA) are only some of our many historical treasures.
