Ohio State 's 1,764 - acre (714 ha) main campus is about 2.5 miles (4.0 km) north of the city 's downtown. The historical center of campus is the Oval, quad of about 11 acres (4.5 ha). Four buildings are listed on the National Register of Historic Places: Hale Hall (originally Enarson Hall), Hayes Hall, Ohio Stadium, and Orton Hall. Unlike earlier public universities such as Ohio University and Miami University, whose campuses have a consistent architectural style, architecture on the Ohio State campus is a mix of traditional, modern and post-modern styles. The William Oxley Thompson Memorial Library, anchoring the Oval 's western end, is Ohio State library 's main branch and largest repository. The Thompson Library was designed in 1913 by the Boston firm of Allen and Collens in the Italianate Renaissance Revival style, and its placement on the Oval was suggested by the Olmsted brothers who had designed New York City 's Central Park. In 2006, the Thompson Library began a $100 million renovation with the stated aims of becoming a "global benchmark twenty - first century '' library while maintaining the building 's classical Italian Renaissance architecture.
