Main Interior Building. The Main Interior Building, officially the Stewart Lee Udall Department of the Interior Building, serves as the headquarters of the United States Department of the Interior. Located in the Federal Triangle of Washington, D.C., this monumental structure was constructed during the Great Depression under the Public Works Administration. It is a prime example of Stripped Classicism architecture and houses the administrative leadership for agencies managing the nation's natural resources and cultural heritage, such as the National Park Service and the Bureau of Indian Affairs.
History
The building's construction began in 1935 as part of a massive federal building campaign orchestrated by the Public Works Administration during the administration of President Franklin D. Roosevelt. Prior to its completion, the United States Department of the Interior was dispersed across several structures, including the Patent Office Building and the Mines and Mining Building. It was officially occupied in 1937, consolidating the department's far-flung offices. In 2010, the building was renamed by an act of Congress to honor former Secretary of the Interior Stewart Lee Udall, who served under Presidents John F. Kennedy and Lyndon B. Johnson. The structure has undergone several major renovations, including a significant modernization project in the 1980s overseen by the General Services Administration.
Architecture
Designed by architect Waddy B. Wood, the building is a monumental example of the Stripped Classicism style prevalent in New Deal-era federal architecture. Its exterior is faced with Indiana limestone and features a colonnaded facade, allegorical sculptures, and a series of bronze entrance doors depicting scenes of American industry. The interior is organized around a grand, skylit courtyard and features extensive use of marble, murals, and decorative metalwork. Notable artistic works include murals by John Steuart Curry and Maynard Dixon, as well as sculptures by Michael Lantz. The building's design emphasizes both governmental authority and public accessibility, with its central hall serving as a public exhibition space for the Department of the Interior Museum.
Functions and tenants
As the headquarters for the United States Department of the Interior, the building houses the office of the United States Secretary of the Interior and the department's senior leadership. It provides administrative offices for several of the department's major bureaus, including the Bureau of Land Management, the United States Fish and Wildlife Service, and the Office of Surface Mining Reclamation and Enforcement. The building also contains the Department of the Interior Museum, which features exhibits on the department's history and its management of natural resources. Other key offices located within the structure handle policy for Native American affairs, water rights, and energy development on federal lands.
Cultural significance
The building is a contributing property to the Pennsylvania Avenue National Historic Site and is listed on the National Register of Historic Places. It has been the backdrop for numerous significant events, including protests by advocates for Native American rights and environmental groups. The structure's art and architecture are considered a lasting legacy of the New Deal's investment in public art and federal infrastructure. It frequently appears in media portrayals of the United States federal government and is a stop on architectural tours of the National Mall area. The renaming for Stewart Lee Udall cemented its association with the modern environmental and conservation movements of the mid-20th century.
