Smithsonian's National Postal Museum

Did you know that Constitution of the United States has a Postal Clause? In Article I, Section 8, Congress is given the right “to establish Post Offices and Post Roads.” Now, nearly 230 years later, the United States Postal Service remains an invaluable independent agency of the federal government—and the subject of one particularly note-worthy museum.

Since 1993, the Smithsonian's National Postal Museum has been “dedicated to the preservation, study and presentation of postal history and philately,” or stamp collecting. While stamps play a prominent role in the museum's physical and online exhibitions, they're not the only objects in its collection. Dating as far back as colonial times, the National Postal Museum's historic highlights include everything from antique ephemera to a “thumping and bumping” mail-carrying stagecoach.

Conveniently situated across from the bustling Washington Union Station, stamped with the Smithsonian seal of approval, and featuring a one-of-a-kind collection, this museum is sure to deliver.

If you have a penchant for portraiture, you won't want to miss the National Portrait Gallery. On the face of it, this monumental museum isn't exactly a “hidden gem.” However, its downtown D.C. location makes it one of only six Smithsonian museums situated outside of the National Mall (the city has 17 Smithsonian museums).

The National Portrait Gallery was established by an act of Congress in 1962. Since then, it has amassed a collection of over 23,000 works featuring “men and women who have made significant contributions to the history, development, and culture of the people of the United States”—including its revered set of presidential portraits.

The National Portrait Gallery shares a beautiful building with the American Art Museum, another Smithsonian museum, making it a top destination for American art enthusiasts.

It may seem like “Smithsonian” is synonymous with “museum” in Washington, D.C. However, institutions like the National Museum of Women in the Arts prove that smaller sites can pack a powerful punch.

As the only major museum with a mission dedicated entirely to promoting women artists, the National Museum of Women in the Arts plays a crucial role in Washington, D.C.'s art and culture scene. In addition to collecting and exhibiting works by groundbreaking artists like Frida Kahlo, Mary Cassatt, and Cindy Sherman, the museum aims to accomplish this mission by “advocat[ing] for better representation of women artists and serv[ing] as a vital center for thought leadership, community engagement, and social change.”

The National Museum of Women in the Arts is based in the Masonic Temple, a former Freemasons building renowned for its Renaissance revival design.

Speaking of beautiful buildings, did you know that there's a museum in Washington, D.C. built around all-things architecture? Since 1980, the National Building Museum has helped visitors “experience stories about the built world and its power to shape our lives, communities, and futures” through a meld of engaging exhibitions, public programs, and unique special exhibitions.

Fittingly, the museum is set inside a striking space, which was formerly the Pension Bureau building. Featuring a stunning Great Hall adorned with 75-foot-tall Corinthian columns, it's no wonder this late 19th-century building has been a favorite site for inaugural balls!

Washington, D.C. may be steeped in star-spangled history, but it is also the home of something more modern: The Phillips Collection. Founded in 1921 by American art collector Duncan Phillips, The Phillips Collection is the country's “first museum of modern art”—a time-honored title it fosters to this day.

Housed in a building that blends Phillip's original Dupont Circle home with newer galleries, the museum's collection features some of modern art's most significant masterpieces, from a collection of contemplative color field paintings by Mark Rothko to Pierre-Auguste Renoir's Luncheon of the Boating Party, its most prized painting.

A far cry from the monumental institutions that line the Mall, this “intimate museum combined with an experiment station” is one of the historic city's most innovative sites.
