Federal Triangle, Government complex in downtown Washington, United States.
Federal Triangle is a triangular government complex in downtown Washington, D.C., bounded by Constitution Avenue, Pennsylvania Avenue, and 15th Street. It houses ten major federal administration buildings, including the Departments of Justice and Commerce and the Environmental Protection Agency.
The Public Buildings Act of 1926 authorized construction of the Federal Triangle and marked the transformation of a deteriorated neighborhood into a government center. Construction began in the late 1920s and reshaped downtown Washington's appearance for decades to come.
The buildings showcase neoclassical architecture with limestone facades and granite foundations, expressing governmental authority through their grand and symmetrical design. Visitors immediately notice how the facades and spacious entrances communicate a deliberate message of order and institutional strength.
The Federal Triangle Metro station provides direct access to multiple federal departments and serves as a key hub for exploring the complex. The area is easy to navigate on foot, and wide sidewalks make it comfortable to walk between the various buildings.
The Internal Revenue Service building's cornerstone was laid in 1929 by Treasury Secretary Andrew Mellon, marking the start of construction during the Great Depression. This project became an important employment program during a time of severe economic hardship.
