U.S. Custom House

721 19th Street
Denver, CO 80202

Located in the heart of the Denver Federal District, the U.S. Custom House is an Italian Renaissance Revival architectural marvel. Architects James Wetmore and Temple H. Buell designed and constructed the "E" shaped building between 1931 and 1937. The main entrance's arched grill and doors are made of solid bronze. Oak and quarry tile were used extensively throughout the building. Colorado yule marble was used on both the interior and exterior of the building — the same marble used to construct the Lincoln Memorial and the Tomb of the Unknown Soldier in Washington, DC. The Custom House is on the National Register of Historic Places.
