The Wichita City Carnegie Library Building located at 220 S. Main Street in Wichita, Kansas, Sedgwick County, Kansas, United States, is a Carnegie library built in 1915. It was listed on the National Register of Historic Places in 1987. The two-story, limestone Beaux Arts building stands in the southwestern part of Wichita's central business district, directly south of the old City Hall. Its façade orientation is west. The building measures approximately one hundred and twenty-eight feet from north to south and eighty-three feet from east to west. After the completion of Wichita's present library in 1966, the Wichita City Carnegie Library Building served as city offices and the municipal court until the Wichita Omnisphere and Science Center established its tenancy in 1976, followed by changing tenants. The two-story, ashlar cut, limestone block building sits on an ashlar cut, limestone block, raised foundation with a multiply moulded watertable. Three bays comprise the rectangular building's façade and rear. The building's main body is one bay deep, a one-bay-by-one-bay brick unit extends from the rear elevation's center bay. A parapetted entry pavilion projects from the facade's center bay. A short, square tower rises from the building's central bay, covered by a rounded, truncated hipped roof sheathed with pantiles and surmounted by a monitor roof. Tripartite windows with translucent glass pierce each wall of the central tower. Standing seam metal covers the gable roofs of the two main wings, the metal may have been tarred. Two skylights, which have been covered due to water leakage, pierce the gable roofs midway. The entry pavilion and the rear extension have low roofs hidden by parapets, they are likely covered with tar and gravel. The building retains its original metal drain pipes on the outer edges of the façade and the rear extension.
