Cozad–Bates House, also known as the Cozad-Bates House Interpretive Center, is the oldest and only surviving pre-Civil War structure in University Circle, Cleveland, Ohio, located at the Mayfield Road and East 115th Street intersection. It is historically known for its involvement in the Underground Railroad. Abolitionist Andrew Cozad built the house in 1853 for his son Justus L. Cozad, who in 1872 added an Italianate front to the structure. Architecturally, it is a rare surviving example of Italianate-influenced residential architecture in America at that time, which includes a hipped roof, curved bay windows, paired eave brackets, and prominent belvedere. The house was listed on the National Register of Historic Places in 1974 and designated as a Cleveland Landmark in 2006.
