What Andalusia Foundation does

The Andalusia Foundation is a 501(c)(3) nonprofit organization that preserves and operates Andalusia Historic House, Gardens & Arboretum, a 50-acre heritage property on a wooded promontory overlooking the Delaware River in Bensalem (Bucks County), Pennsylvania. Founded in 1980 by James Biddle, the Foundation maintains the Big House, a National Historic Landmark since 1966 and one of the finest examples of Greek Revival architecture in the United States, along with formal gardens, the Grotto, outbuildings, and an arboretum containing over 800 trees that holds Level II ArbNet accreditation.

The Foundation generates revenue through a diversified mix of visitor admissions, annual memberships, private group tours, weddings and special-event venue rentals, signature fundraising events, and tax-deductible donations. Core paid offerings include self-guided garden admission ($20/person), guided Big House tours ($30/person), group tours priced at $30-$45 per person for groups up to 56, and Champagne Garden Tours at $65 per person. A seven-tier membership program spans $60 (Individual) to $5,000 (Collector Benefactor). The wedding venue rental stream commands a starting site fee of $25,000, while the annual Cabaret by the River black-tie gala and the sold-out Garden Symposium anchor event-based revenue, supplemented by yoga sessions, weekly Friday tours, and Open Saturdays. Approximately 31 staff, a 19-member Board of Trustees, and a volunteer gardener program support operations, with strategic partnerships spanning the Royal Horticultural Society (the only U.S. Partner Garden, named 2024 Partner Garden of the Year in the Overseas Category), Terrain (Anthropologie Group), Greater Philadelphia Gardens, and the Garden Club of America.
