Andalusia Historic House, Gardens and Arboretum


Andalusia Historic House, Gardens and Arboretum is located on a wooded promontory overlooking the Delaware River 13 miles upstream from Philadelphia. The 100-acre property is the ancestral home of the Biddle family and is a natural paradise of native woodlands and spectacular formal gardens.  The centerpiece of Andalusia is the “Big House”, the early nineteenth century Greek Revival mansion with its monumental columned porch, placed on the National Register of Historic Landmarks in 1966.  The estate, carefully maintained in the 19th century tradition, is home to more than 800 trees in the living collection including nearly 250 unique specimen and cultivars from around the world. The Andalusia Foundation was created in 1980 in order to maintain and preserve this national living treasure for the benefit of the public.
