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

The palatial, Gilded Age Anderson House is the headquarters of the Society of the Cincinnati, the nation's oldest historical organization promoting knowledge and appreciation of America's independence. The society was founded by Revolutionary War veterans in 1783—George Washington was its first president general—and this has been its home since 1938. Guided tours of the first and second floors reveal the history of the society, the significance of the American Revolution, and the lives and collections of the home's first owners, Larz and Isabel Anderson. Built in 1905, the home was the Andersons' winter residence and retains much of its original contents—an eclectic mix of furniture, tapestries, paintings, sculpture, and Asian art. Larz, a U.S. diplomat from 1891 to 1913, and his wife, Isabel, an author and benefactress, assembled their collection as they traveled the world during diplomatic postings. Today, the house also features an exhibition gallery, open every day except Monday, and a research library that you can visit by appointment.

Decatur House was built in 1818–19 on Lafayette Square, just across from the White House, for naval hero Stephen Decatur and his wife, Susan. Designed by Benjamin Henry Latrobe, the country's first professional architect, it's one of Washington's oldest surviving homes. But Decatur didn't have long to enjoy it, since he died tragically 14 months later, after a duel with Commodore James Barron. Wealthy hotel and tavern owner John Gadsby purchased the distinguished Federal-style house as a retirement home in 1836. The large two-story dependency was used as quarters for numerous enslaved individuals in his household—Washington's only extant slave quarters. Tours—offered Monday at 10:30 am and 1 pm—feature these historic quarters and the house's first and second floors, much of which represent the taste of a later owner, Marie Beale, beloved for her salons with ambassadors and politicians. The White House Historical Society operates one of its three retail shops here, and you'll find an excellent selection of White House history–themed products, including the annual Christmas ornament.

Not to be confused with the Dumbarton Oaks museum, a beautiful garden and research center a few blocks away, this circa-1799 brick mansion was once the home of the first U.S. Register of the Treasury, Joseph Nourse. Today it's the headquarters for The Colonial Dames of America. Visitors can tour the antiques-filled Federalist home, which often hosts concerts, theatrical performances, and other community events. Docent-led tours are available on the weekend, and the house is open for self-guided tours from Friday to Sunday. Timed tickets are required.

This opulent, Romanesque Revival mansion, also known as the Brewmaster's Castle, was the home of Christian Heurich, a German immigrant who made his fortune in the beer business. Heurich's brewery was in Foggy Bottom, where the Kennedy Center stands today. The building, a National Register of Historic Places landmark, is considered one of the most intact Victorian houses in the country, and all the furnishings were owned and used by the Heurichs. The interior is an eclectic mix of plaster detailing, carved wooden doors, and painted ceilings. The downstairs Breakfast Room, which also served as Heurich's bierstube (or beer hall), is decorated like a Rathskeller with the German motto "A good drink makes old people young." Heurich must have taken the proverb seriously. He drank beer daily, had three wives, and lived to be 102. Head to the website to see up-to-date hours and latest programming, which in the past has included guided tours, a holiday market, and outdoor happy hours.

Cereal heiress Marjorie Merriweather Post was a celebrated philanthropist, businessperson, and socialite, who was also known for her passion for collecting art and creating some of the most beautiful homes of the 20th century. Of these, the 25-acre Hillwood Estate, which Post bought in 1955, is the only one now open to the public. The 36-room Georgian mansion, where she regularly hosted presidents, diplomats, and royalty, is sumptuously appointed, with a formal Louis XVI drawing room, private movie theater and ballroom, and magnificent libraries filled with portraits of the glamorous hostess and her family and acquaintances, as well as works from her rich art collection. She was especially fascinated with Russian art, and her collection of Russian icons, tapestries, gold and silver work, imperial porcelain, and Fabergé eggs is considered to be the largest and most significant outside Russia. She devoted equal attention to her gardens; you can wander through 13 acres of them. Allow two to three hours to tour.

The site of the first headquarters for the National Council of Negro Women, the Mary McLeod Bethune Council House celebrates the life and legacy of Bethune, who founded the council and also served as president of the National Association of Colored Women. It was the council’s headquarters from 1943 to 1966, and Bethune herself lived here from 1943 to 1949. The archives of the history of African American women in the United States and Bethune’s legacy are housed here as well. After a lengthy construction project to update the archival research areas and to stabilize the physical foundations, the site reopened to the public in 2018.

Washington's oldest surviving building, this fieldstone house in the heart of Georgetown, was built in 1765 by a cabinetmaker named Christopher Layman. A succession of occupants used the house as a residence and business place until 1953 when the National Park Service purchased it. Over the next seven years, it underwent an extensive restoration that has preserved the building's Revolutionary War–era architecture and design. The furnishings of several of the rooms reflect the times, with the simple, sturdy artifacts—plain tables, spinning wheels, and so forth—of 18th-century middle-class life. You can take a self-guided tour of the house and its lovely English-style gardens.

In June 1862, President Lincoln moved from the White House to this Gothic Revival cottage on the grounds of the Soldiers' Home to escape the oppressive heat of Washington and to grieve for the loss of his son Willie. Lincoln and his wife, Mary, lived in the cottage until November of that year, and because they found it to be a welcome respite from wartime tensions, they returned again during the summers of 1863 and 1864. Lincoln ultimately spent a quarter of his presidency at this quiet retreat; he was here just one day before he was assassinated. One of the most significant historic sites of Lincoln's presidency, it was here that he developed his ideas for what would become the Emancipation Proclamation. Visitors may picnic on the cottage grounds, which have been landscaped to look as they did when Lincoln lived here.

As you go up the hill toward the Cottage, there's a panoramic view of the city, including the Capitol dome. The 251-acre Soldiers' Home sits atop the third-tallest point in D.C.

This is D.C.’s funkiest museum. A reimagining of your grandma’s attic by surreal filmmaker Federico Fellini, it has dozens of secret doors and passageways, as well as rooms overflowing with antiques, pictures, figures of medieval angels, and memorabilia, including 60 signed Gibson guitars, stuffed animals, chandeliers, and books. The museum, housed in five interconnecting town houses, also doubles as an inn, where rooms pay homage to notables such as John Lennon, Winston Churchill, and Rosa Parks, once a frequent visitor. You can get a peek at the themed rooms when they're not occupied by rock stars or CEOs, who value the mansion’s privacy and security.

Designed by Dr. William Thornton (original architect of the U.S. Capitol), the Octagon House was built by enslaved workers for John Tayloe III, a wealthy plantation owner, and completed in 1801. Thornton chose the unusual shape to conform to the acute angle formed by L'Enfant's intersection of New York Avenue and 18th Street. After the British burned the White House in 1814, Thornton convinced the Tayloes to allow James and Dolley Madison to stay in the Octagon. From September 1814 until March 1815, the Octagon became the temporary White House. In the second-floor study, the Treaty of Ghent, which ended the War of 1812, was ratified. The American Institute of Architects (AIA) established its national headquarters at the Octagon in 1898 and renovated the building as one of the country's first preservation projects. AIA stayed there for 70 years before moving into new modern headquarters directly behind. Self-guided tours take in historically furnished rooms; second-floor gallery spaces hold rotating exhibits on architecture, design, and history.

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.

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.

President Wilson and his second wife, Edith Bolling Wilson, retired in 1921 to this Georgian Revival house designed by Washington architect Waddy B. Wood. It was on this quiet street that Wilson lived out the last few years of his life. It is the only presidential museum in the nation’s capital. Wilson died in 1924—Edith survived him by 37 years—and bequeathed the house and its contents to the National Trust for Historic Preservation. Tours of the home can be general or themed or even virtual, and they provide a wonderful glimpse into the lives of this couple and the dignitaries who visited them here. Items on display include his cane collection, a Gobelin tapestry, a mosaic from Pope Benedict XV, the pen used by Wilson to sign the declaration that launched the United States into World War I, and the shell casing from the first shot fired by U.S. forces in the war. The house also contains memorabilia related to the history of the short-lived but influential League of Nations, including the colorful flag Wilson hoped would be adopted by that organization.
