English: Built in 1822-1827, this Greek Revival-style building was designed by Robert Mills to serve as the South Carolina State Hospital, which was open to paying patients with psychiatric illnesses. The psychiatric hospital was the second to open in the United States, after Virginia founded theirs in 1773 at Williamsburg. The Mills Building is the oldest remaining original psychiatric hospital building in the United States, and allowed some people of color to be admitted early on in its history, though this was only formalized in 1848, and a new, racially segregated psychiatric hospital for people of color was opened in 1910 north of the city of Columbia. The building served as a temporary prisoner of war camp in 1865, housing prisoners relocated from Camp Sorghum. The building features a red flemish bond brick exterior, doric pilasters, arched bays on the second floor, twelve-over-twelve double-hung windows, oxeye windows at the attic of the central wing, a domed cupola on the roof of the central wing with a dome, a rusticated brick base, two angled wings on ether side of the central wing, which connect to rectilinear wings added in 1838 and 1842, a two-story front portico at the second and third floors with Doric columns, an arcade at the base with arched openings and rusticated stone cladding, a front entrance door with a fanlight transom, and a front pediment with a fanlight attic window, and a semi-circular staircase in the center of the rear facade. The building was utilized to house patients until 1937, when it became home to the hospital’s nursing school, with a dormitory for nursing students, nurses, classrooms, offices, and a library, until the nursing school closed in 1950. Following the closure of the school, the building remained in use as a dormitory for nurses, as well as continuing to house classrooms, the hospital library, and offices. The building was listed on the National Register of Historic Places in 1970, and was designated a National Historic Landmark in 1973. The hospital closed in 1996, at which point the building was home to the South Carolina Department of Health and Environmental Control, which remains in the building, and saw the addition of a modern office wing to the rear of the original structure, as well as the restoration of the exterior of the original building.
