The oldest of the three United States Library of Congress buildings, the Thomas Jefferson Building was built between 1890 and 1897. It was originally known as the Library of Congress Building and is located on First Street SE, between Independence Avenue and East Capitol Street in Washington, D.C. The Beaux-Arts style building is known for its classicizing facade and elaborately decorated interior. Its design and construction has a tortuous history; the building's main architect was Paul J. Pelz, initially in partnership with John L. Smithmeyer, and succeeded by Edward Pearce Casey during the last few years of construction.
