Federal Triangle, Washington — Area Guide & Where to Stay
Federal Triangle is a wedge of federal government buildings in central Washington. Its name comes from the triangular block that Pennsylvania Avenue and Constitution Avenue form as they meet toward the east. The area lines the northern side of the National Mall, so its offices sit a short walk from the Smithsonian museums that face them across Constitution Avenue. Beds are scarce here.
About Federal Triangle
Where to stay in Federal Triangle
Each area has its own feel; here's who each one suits.
Federal Triangle is a working government precinct, not a hotel district. Its blocks fill with office staff by day and empty after dark, so evenings stay quiet and places to eat are few. The payoff is proximity.
The Smithsonian museums of the National Mall, among them the National Museum of Natural History and the National Museum of American History, stand a short walk south across Constitution Avenue. Anyone wanting a real choice of rooms should look north to Penn Quarter and downtown Washington, where the hotels cluster.
About Federal Triangle
What are the main landmarks in Federal Triangle?
Few sights sit inside the triangle itself. The nearest belong to the National Mall's northern row, which faces the district across Constitution Avenue: the National Museum of Natural History, the National Museum of American History, and the National Museum of African American History and Culture. Across the Mall to the south stand the National Air and Space Museum, the Hirshhorn Museum and Sculpture Garden, the National Museum of African Art, and the Freer Gallery of Art.
A few blocks north, in Penn Quarter, one grand building holds the Smithsonian American Art Museum and the National Portrait Gallery. The Lincoln Memorial and the Vietnam Veterans Memorial lie a longer walk west along the Mall.
What is the history of Federal Triangle?
Before its offices rose, the low ground between Pennsylvania Avenue and the Mall was a tenement and red-light quarter called Murder Bay. The City Beautiful movement, drawing on the McMillan Plan, marked the whole triangle for clearance. Building went ahead between 1926 and 1938, when one coordinated design filled the site with classical stone facades ranged around interior plazas.
The look was deliberate. Matching cornice lines and colonnades were drawn so the separate agencies would read as one continuous government wall, and the final block was not finished until 1998.
Where is Federal Triangle?
Constitution Avenue forms the southern edge, with the National Mall directly opposite. Pennsylvania Avenue cuts the northwestern side on a diagonal, while 15th Street closes the western end by the White House grounds. The block then narrows eastward to a sharp apex that points toward the Capitol, with Penn Quarter and the downtown core just to the north.
No river runs through it.
