Friends Hospital

Philadelphia, Philadelphia, Pennsylvania Listed Ref. 99000629 National Historic Landmark District

Also known as: Friends' Asylum For The Relief of Persons Deprived Of Reason; Friend's Asylum For The Insane

Why it's listed

Friends Hospital occupies a wooded and landscaped site of about 100 acres overlooking Tacony Creek in Frankford, Philadelphia. The institution opened in April 1817 as the Friends Asylum for the Relief of Persons Deprived of the Use of Their Reason, with a capacity for fifty patients. Its design drew on the York Retreat in England, modified by Thomas Scattergood to place patients' rooms on one side of the corridor for privacy, quiet, and light. Isaac and Ann Bonsall, the first superintendents, ran the asylum as a family, with staff and patients eating and working together. Patients took part in farming and horticulture, and the grounds later became known for their azalea plantings and the Garden Days event. The hospital is significant as the first private, nonprofit mental hospital in the United States and for its moral treatment methods, which influenced psychiatric care elsewhere.

Significance in brief: The document argues that the hospital was the first private, nonprofit, exclusively mental hospital in the United States and the oldest continuing such institution. Its Quaker-based 'moral treatment' approach, its site plan and design, and its use of horticulture in therapy became models for other American psychiatric facilities. It also employed women doctors and professional nurses early on.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
