The Kirkbride Plan was a revolutionary approach to the design of
19th-century psychiatric hospitals. Developed by physician Thomas Story Kirkbride, the plan was based on the belief that the physical environment could play an important role in the treatment and recovery of people with mental illness.

Kirkbride hospitals were designed around a central administration building with long, connected wings extending outward in a distinctive symmetrical arrangement. The design provided patients with access to natural light, fresh air, gardens, and carefully planned spaces while separating different areas of the hospital.

More than simply an architectural style, the Kirkbride Plan reflected a changing philosophy of mental healthcare—one that emphasized humane treatment, structure, nature, and the therapeutic environment.
