The oval was named in 2004 in commemoration of the university's 150th anniversary. The Schroeder Family School of Business, McCurdy Alumni Memorial Union, Sampson Hall / Mann Health Center, Hyde Hall, Olmsted Administration Hall, Clifford Memorial Library, and Koch (pronounced Cook) Center for Science and Engineering (all sectors of the original and later additional science/engineering buildings) surround Sesquicentennial Oval. Most of the buildings follow an old limestone motif, and renovations generally emulate the rest of the building.
