Telescope, which in 1931—the year of its completion—was the third-largest telescope in the world only after the 100-inch at Mt. Wilson, California, and the 72-inch at Victoria, B.C., Canada. The Perkins Telescope was moved to Arizona's Lowell Observatory in 1961 where it was used by Vera Rubin to study Dark Matter. The Perkins Telescope has since been replaced by The Schottland 32-inch Reflector. The grounds near Perkins also housed Ohio State's radio telescope, known locally as The Big Ear; the Big Ear was disassembled in 1998. Other buildings Several of the campus buildings are listed on the National Register of Historic Places: Austin Manor, Edwards Gymnasium, Elliott Hall, Merrick Hall, Perkins Astronomical Observatory, Sanborn Hall, Slocum Hall, Sturges Hall, Stuyvesant Hall and The University Hall.
