Curved Hallway with Weathered Walls at Fergus Falls Kirkbride Building

The Fergus Falls Kirkbride Building, part of the former Fergus Falls State Hospital, was designed by architect Warren B. Dunnell and completed in 1890 following the Kirkbride Plan, a 19th-century model for psychiatric care that favored long, curved wings to maximize light and air circulation for patients. The hospital operated under changing names, including the Fergus Falls Regional Treatment Center, until its state-run mental health programs ceased in 2005. Hexagonal tile flooring and glass-block windows found throughout the building's corridors are typical of early 20th-century institutional construction, chosen for durability and daylight transmission. The complex is listed on the National Register of Historic Places, and portions of the campus have since been redeveloped for private use while much of the original Kirkbride structure remains vacant.
