The Mentor Building

The Chicago Building, also known as the Mentor Building, is a historic high-rise at the famous intersection of State and Madison Streets in Chicago. Built in 1905 in the Neo-Renaissance style, the building originally housed the Chicago Savings Bank as well as numerous doctors' offices. Architecturally, it stands out for its dark reddish-brown terra-cotta facade, classic Chicago windows, and projecting oriel windows. A special feature is the cornerstone on the third floor, which serves as the zero point for the city's address numbering system. Since 1997, the School of the Art Institute has used the building as a dormitory, while a clothing store now occupies the ground floor.
