Ohio State's main urban campus is in Columbus.
It has a size of 1755 acres, and it is about 2.5 miles (4.0 km) north of the city's downtown.
Four buildings are currently listed on the National Register of Historic Places: Enarson Hall, Hayes Hall, Ohio Stadium, and Orton Hall.
Architecture on the Ohio State campus is a mix of traditional, modern, and post-modern styles.

The William Oxley Thompson Memorial Library is located at the west end of The Oval.
It is the Ohio State library's main branch, and it is the largest of the school's branches.
The school's library system has twenty-one libraries on its Columbus campus.
There are eight other branches in other locations, and the system has fifty-five branches and collections in all.

The Wexner Center for the Arts is at the east end of The Oval.
It was designed by the architects Peter Eisenman of New York and Richard Trott of Columbus, and it opened in 1989.
The center was built mostly from a twenty-five million dollar gift from Ohio State graduate Leslie Wexner.
Part of its design was to honor to the armory (military storage location) that was replaced with the Wexner Center.
Its deconstructivist architecture makes known as one of the most important buildings of its generation, but the design makes it less than ideal to show many of the art displays.
The main, permanent work kept in the center is Picasso's Nude on a Black Armchair, a forty-five million dollar painting that Wexner gave to Ohio State.

Ohio Union is on the east side of The Oval, and at the south side is another, smaller grassy area known as The South Oval.
The west side is contains Browning Amphitheatre and Mirror Lake.

The Ohio State College of Medicine is on the southern edge of the central campus.
It is home to the James Cancer Hospital, where cancer is studied.
It is one of the National Cancer Institute's forty-one NCI-designated Cancer Centers.
