1915: Wichita City Library, 220 S. Main. Built in 1914 with a $75,000 gift from philanthropist Andrew Carnegie, Wichita's old library served the city until the new facility was built directly across the street in 1967. (Note the city jail's guard tower in the above left photo.) The building was later occupied by the Omnisphere science center, which closed in 2001. It currently sits empty.
