Welcome to the Whitemarsh Foundation


The Whitemarsh Foundation is a tax-exempt public charity established in 2001, dedicated to the preservation, conservation and stewardship of the Whitemarsh Valley.

“Every piece of land has a story, and the 450 acres that comprise Erdenheim Farm speak about the rich agricultural history of our region, the role of open space in protecting our waterways and uplifting our spirits.

The Whitemarsh Foundation wants to ensure that the story of Erdenheim Farm continues to speak for generations to come, helping to connect future residents of the Philadelphia region with the agrarian landscapes that once defined this area and providing a permanent reminder of the restorative power of nature and open space.

Please join us today in our efforts to steward this unique American masterpiece and open space treasure.”
