Located on a wooded promontory overlooking the Delaware River, Andalusia has been a stately presence on this stretch of water, just north of Philadelphia, for more than two hundred years. The ancestral home of the Biddle family, Andalusia is also a natural paradise of native woodlands and spectacular gardens that have evolved over time. Placed on the National Register of Historic Landmarks in 1966, the Big House - one of the finest examples of Greek Revival architecture in the United States - provides an unparalleled look into our nation's past, while also offering a glimpse into the life of a family that helped to shape its future. Its surrounding gardens delight the senses all through the year, from the tumbling, brightly-colored leaves of fall to the floral extravaganza of spring and the abundance and scent of summer.
