Smithsonian Institution

The Smithsonian Institution is a group of museums, research centers, and the National Zoological Park based in Washington, D.C., founded in 1846 from the bequest of British scientist James Smithson. It is the largest museum complex in the United States and a major center for research and public education.

The Institution includes 19 museums and galleries and the National Zoo, with major public attractions such as the National Air and Space Museum, the National Museum of Natural History, and the National Museum of American History. Many museums feature extensive permanent collections and rotating special exhibitions; popular single museums can require half a day or more to see thoroughly.

As an administrative and research organization, the Smithsonian supports scientific research, collections care, and public programs across its museums and facilities. The Institution has expanded since its founding to include libraries, research centers, and outreach programs nationwide.

Most Smithsonian museums and galleries are located along the National Mall in central Washington, D.C.; the National Zoo sits in the northwest part of the city. Several research and storage facilities are located elsewhere in the United States and abroad.

• Admission: Admission is generally free for Smithsonian museums on the National Mall; some special exhibitions or programs may require a fee or timed entry.
• Logistics: Museums are clustered along the National Mall, so plan visits geographically and allow several hours for the larger sites such as the Air and Space and Natural History museums.
