While mapped here is the Dupont Circle station, every single station in Washington, D.C.'s Metro system is an example of Brutalist architecture. Despite commuters' many complaints on the transit system, the concrete panels and vaulted-ceiling stations have caught the eye of the American Institute of Architects (AIA) more than once. In 2014, the AIA awarded the Metro system the AIA Twenty-five Year Award. This award recognized the system for standing the test of time, architectural excellence, and excellence in function. Seven years earlier, the AIA listed the Metro as one of America's 150 favorite architecture. It was the only Brutalist design on the list.

The building that houses the Consumer Financial Protection Bureau (CFPB) is indicative of Brutalist architecture with its blocky concrete shape. The CFPB is planning a renovation on the building that is expected to cost taxpayers a whopping $207 million if all renovation options are implemented. This price is approximate to the price of a Class A office building. [Photo via Mark Plummer]

Completed in 1969, the monolithic Sunderland Building rises eight stories. As seen in most Brutalism buildings, the windows are set deep into the walls.

Since 1977, the James V. Forrestal building has housed the U.S. Department of Energy. It was originally known as the Federal Office Building 5. The building finished construction in 1969 and consists of three structures, each connected by two floors of underground office space. In 1964 while the building was undergoing construction, Washington Post architectural critic Wolf von Eckardt described the structure as "a work of architecture we will probably be proud of," before one year later describing the structure's great length along 10th Street SW as a "pity." New York Times architecture critic Ada Louise Huxtable believed that the design "failed miserably."

The U.S. Department of Labor is located in the the Frances Perkins Building. Before being constructed in 1975, the federal building had to obtain air rights in order to be constructed over the I-395 freeway.

Outside of L'Enfant Plaza Metro station, you can find the headquarters for the U.S. Department of Education. This expansive, blocky building is located alongside many other federal buildings in the neighborhood.

The 10-story Robert C. Weaver Federal building was named after the first Secretary of Housing and Urban Development and the first African American Cabinet member. The architect of the building is Marcel Breuer, who is also known for having designed the Whitney Museum of American Art in New York City. In 2008, the development was added to the National Register of Historic Places.

In George Washington University, you'll find this Brutalist library that rises seven stories and contains over two million volumes. The building was constructed in the 1970s and was renovated in 2012 for $16 million in order to provide more natural lighting and open space as well as a digital media lab.

The Lauinger Library is the main library for Georgetown University. Constructed in 1970, this library holds 1.7 million volumes as well as archival documents related to Georgetown.

The J. Edgar Hoover building has been described everything from something out of outer space by NPR's Catesby Leigh to a black hole and an urban sin by Washingtonian's Arthur Cotton Moore. It is also described as "one of the most valuable development opportunities ever to become available in downtown Washington" by The Washington Post as the FBI debates where its next headquarters will be, leaving the nearly 6.7 acre-property up for grabs.

With a double-arched design, the Washington Hilton Hotel was built in 1965 by William B. Tabler, Sr., an American architect who designed more than 400 hotels. Since the hotel opened, it has hosted events like the White House Correspondents Association annual dinner as well as musical performances by artists like The Doors and Jimi Hendrix. In March 30, 1981, the hotel was also the site of an assassination attempt on U.S. President Ronald Reagan.

This hotel is known for scandal, a still unexplained garage collapse, and a fairly pricey renovation that is expected to give the Brutalist building's guest rooms an "urban resort" feel.
