Adler and Sullivan's early work in the Jewelers Building

The Jewelers Building is located at 15–17 Wabash Avenue between East Monroe and East Madison Streets in the Loop community area of Chicago. Built in 1881–82, it was designed by Dankmar Adler and Louis Sullivan and is the only example of the early work of Adler & Sullivan that survives in the Loop. It is also known as the Iwan Ries Building and the "Little" Jewelers Building to distinguish it from the larger structure at 35 East Wacker Drive.

While the building follows a common loft construction and plan, its facade departs dramatically from others of its type. The exterior features an open design using cast iron mullions rather than masonry piers in the central bay. It also features Sullivan's stylized floral ornament.

The building was listed on the National Register of Historic Places on August 7, 1974, and was designated a Chicago Landmark on December 18, 1981. It is situated in Chicago's Jewelers Row District.
