Old Central, historically known as the College Building, is the oldest building on the Oklahoma State University campus in Stillwater, Oklahoma. Originally built in 1894, it was the first permanent building on the Oklahoma A&M campus. Old Central's bell clapper once served as a traveling trophy in the Bedlam Series athletics rivalry between Oklahoma State University and the University of Oklahoma. The new "Bedlam Bell" is a crystal trophy modeled after Old Central's bell and is awarded to the winner of each individual athletics contest in addition to the overall series winner for each year.
