68 Best Sights in Washington, D.C., USA

Stop at Q Street between 31st and 32nd Streets, and look through the trees to the north, to the top of a sloping lawn, to see the neoclassical Tudor Place, designed by Capitol architect Dr. William Thornton for one of Martha Washington's granddaughters. Completed in 1816, the house remained in the family for six generations, hosting countless politicians, dignitaries, and military leaders. On the house tour, you can see the most extensive collection of George and Martha Washington items on public display outside Mount Vernon, Francis Scott Key's law desk, and spurs belonging to soldiers executed for serving as spies during the Civil War. You can only visit the house by guided tour (given hourly; the last tour at 3 pm), but before and afterward, until 4 pm, you can wander freely with a map through the formal garden full of roses and boxwoods, many of which are more than a century old. Admission to the garden grounds is free, but reserved tickets are required.

The outside of the building is plain, but inside, a wealth of art, contained in two separate collections, reflects the department's work. The Office of the Secretary Art Collection, featuring heroic oil paintings of dam construction, gold panning, and cattle drives, is found throughout the building's hallways, offices, and meeting rooms. The Department of the Interior Museum Collection outlines the work of the Bureau of Land Management, the U.S. Geological Survey, the Bureau of Indian Affairs, the National Park Service, and other department branches. On Tuesday and Thursday at 2 pm, you can view 26 photographic murals by Ansel Adams and more than 40 dramatic murals painted by Maynard Dixon, John Steuart Curry, and other artists. Reservations are required for the Murals Tour; call at least two weeks in advance. The Indian Craft Shop across the hall from the museum sells Native American pottery, dolls, carvings, jewelry, baskets, and books.

Once used to store currency, this is one of the most impressive Greek Revival buildings in the United States. Robert Mills, the architect responsible for the Washington Monument and the Smithsonian American Art Museum, designed the colonnade on 15th Street. After the death of President Lincoln, the Andrew Johnson Suite was used as the executive office while Mrs. Lincoln moved out of the White House. One of the highlights is the Cash Room. Initially opened in 1869, it served as a bank, providing essential services to the public and supplying local banks with coins and currency. Renovated in 1985, visitors can tour the historic room. Tours of the Treasury Building are available only to U.S. citizens or legal residents, and you must make the reservation in advance through your congressional office.

Although Pierre L'Enfant included a Navy Memorial in his plans for Washington, D.C., the memorial did not come to life until 1987. The main attraction here is a 100-foot-diameter granite map of the world, known as the Granite Sea. Fountains, benches, and six ship masts surround the map. The Lone Sailor, a 7-foot-tall statue, stands on the map in the Pacific Ocean between the United States and Japan. The Naval Heritage Center, next to the memorial in the Market Square East Building, displays videos and exhibits of uniforms, medals, and other aspects of navy life. If you've served in the navy, you can enter your service record into the log. Bronze relief panels on the Pennsylvania Avenue side of the memorial depict 26 scenes commemorating events in the nation's naval history and honoring naval communities.

The White House Visitor Center is a fantastic way to get an orientation before visiting the White House and an excellent alternative for those who could not get tickets. Displays, artifacts, photos, videos, and interactive exhibits recount the life and times of America's most famous house, providing behind-the-scenes insight into the workings of the White House. Afterward, go for a walk around the grounds of the President's park for the iconic views of the White House.

You don't have to be a Democrat to enjoy this historic building, which became the headquarters for the Women's National Democratic Club in 1927. The exquisitely decorated mansion, built in the 1890s and designed by D.C. architect Harvey Page for opera singer Sarah Adams Whittemore, has housed senators and cabinet members over the years. Now it's best known for its library, where Eleanor Roosevelt did her radio broadcasts, and its full-length portraits of first ladies, painted in a whimsical style by folk artist April Newhouse.

In late 2014, Congress re-designated this quiet, sunken garden to honor General John J. "Black Jack" Pershing, the first—a century ago—to hold the title General of the Armies. An official unit of the National Park System, the memorial currently includes engravings on the stone walls recounting pivotal campaigns from World War I, when Pershing commanded the American Expeditionary Force and conducted other military exploits. Steps and small tables surround a fountain and duck pond, making for a pleasant midday respite. The park had a $46-million renovation of the memorial in 2021. 

Although there's not a lot to see inside, this gargantuan complex does have a one-room visitor center with a historical timeline, photo displays, and a video, all highlighting the nation's agricultural roots, current policies, and future challenges.
