Reliance Building

The Reliance Building is a skyscraper located at 1 W. Washington Street in the Loop community area of Chicago, Illinois. The first floor and basement were designed by John Root of the Burnham and Root architectural firm in 1890, with the rest of the building completed by Charles B. Atwood in 1895. It is the first skyscraper to have large plate glass windows make up the majority of its surface area, foreshadowing a design feature that would become dominant in the 20th century.

The Reliance Building was listed on the National Register of Historic Places in 1970; and on January 7, 1976, it was designated a National Historic Landmark.

The Reliance Building is also part of the Loop Retail Historic District, a collection of over one hundred buildings that reflects the growth of State and Wabash Streets as the central retail district of Chicago. The building fell into disrepair starting in the 1940s, and was restored in the late 1990s. Since 1999, the building has housed the 122-room Hotel Burnham and Atwood Cafe.
