Historically known as the College Building, Old Central is the oldest building on the Oklahoma State University campus in Stillwater. Constructed in 1894, it was the first permanent building on the Oklahoma A&M campus and was originally the only academic building until 1900. The building's bell clapper symbolized university life and later a key element in the Bedlam rivalry between OSU and the University of Oklahoma. Designed by architect Herman M. Hadley, the building was constructed in 1894 using a mix of brick, timber and sandstone. Its eclectic design features a tower that has a somewhat Germanic appearance, reflecting the architectural styles of the late 19th century. Despite structural challenges over the years, including serious cracks and condemnation in 1925, Old Central was restored and placed on the National Register of Historic Places in 1971. Today, it stands as a testament to the university's rich history and enduring legacy.
