The Andalusia Foundation is a charitable organization dedicated to preserving, maintaining, and interpreting Andalusia, a national historic landmark estate that features the Greek Revival Big House, formal gardens, an arboretum, native woodlands, and historic outbuildings. The non-profit company is based in Andalusia, PA. The foundation manages the property to ensure public access, education, and stewardship of its history and horticultural legacy, and provides educational programs, volunteer opportunities, and a journal highlighting news and exhibitions related to the Biddle family and the estate’s collections. Membership levels offer benefits such as free admission, guest passes, and invitations to exclusive events. The foundation also honors horticultural stewardship through awards and partners with organizations to support community engagement and garden care. The company was founded in 1795 by John Craig.
