What Is the Smithsonian Institution?
The Smithsonian Institution is one of the most extraordinary cultural organisations on the planet. Founded in 1846 following a bequest by British scientist James Smithson, it has grown into a vast network of museums, galleries, research centres, and a zoo — all operated by the United States government and all free to enter.
Today, the Smithsonian encompasses 19 museums and galleries, most of them clustered along the National Mall in Washington, D.C., with additional facilities in New York City. Its collections total over 155 million objects, making it the largest museum complex in the world.

Must-See Highlights
National Air and Space Museum
Consistently the most visited museum in the United States, the Air and Space Museum houses the Wright Brothers' Flyer, Charles Lindbergh's Spirit of St. Louis, and actual Apollo lunar modules. A new renovation has dramatically improved the visitor experience and added new interactive galleries.
National Museum of Natural History
The Hope Diamond — one of the most famous gemstones in history — sits at the heart of this museum's geology gallery. Beyond that, the museum features a spectacular fossil hall with assembled dinosaur skeletons, an ocean hall with a life-size right whale model, and exhibits on human origins.
National Museum of African American History and Culture
Opened in 2016, this is one of the newest and most impactful additions to the Smithsonian. It tells the story of African American history from slavery through to the present day, using powerful objects, oral histories, and immersive displays. Timed-entry passes are required and fill up quickly — book well in advance.
Planning Your Smithsonian Visit
- Entry is free to all Smithsonian museums and the National Zoo.
- Most National Mall museums are open daily from 10am–5:30pm (hours vary and may be extended seasonally).
- The National Mall museums are within walking distance of each other — but don't try to visit more than two or three in a single day.
- Pick up a National Mall map at any museum entrance to orient yourself.
- Parking on the Mall is limited; metro (Blue, Orange, or Silver lines) is strongly recommended.
Beyond Washington, D.C.
Two Smithsonian museums are located in New York City: the National Museum of the American Indian (in Lower Manhattan) and the Cooper Hewitt, Smithsonian Design Museum (on the Upper East Side). Both are exceptional and worth visiting if you're in New York.
Whether you have a day or a week, the Smithsonian is a cultural treasure that rewards exploration. Given that admission is always free, there's no excuse not to keep coming back.
