[3] The current University Hall was reconstructed in its place, taking a similar exterior appearance to the original building, but updating the inner workings.

Notable exterior differences include elimination of the east and west entrances and chimneys and alteration of the clocktower by relocating the clock and removing the roof's gables.

[6][7] Hayes Hall is currently occupied by the Department of Design, part of The Ohio State University College of Arts and Sciences as of 2024.

The capitals of the numbered columns in the entrance hall feature carvings of fossils, such as trilobites, as well as other objects such as the races of Man.

Because of its unique architectural features, which have made it a campus landmark, Orton Hall has been entered into the National Register of Historic Places.

The replica was cast from a skeleton found in Antarctica by Ohio State University geologist David Elliot in 1991.
