Smithsonian National Museum of Natural History is a free Smithsonian museum at 10th Street & Constitution Avenue NW, Washington, District of Columbia 20560, United States of America, on the National Mall. Opened in 1910 to house and interpret the Smithsonian’s growing scientific collections, the Beaux-Arts landmark brings together fossils, minerals, animals, human evolution, and ocean science. Travelers come for the Hope Diamond, dinosaur specimens, the central Rotunda’s giant elephant, and galleries that make major research collections accessible to all ages.
What to Expect at Smithsonian National Museum of Natural History
Begin beneath Henry, the 11-ton African bush elephant in the soaring Rotunda, then choose a wing rather than trying to see every gallery at once. The David H. Koch Hall of Human Origins follows more than six million years of human evolution through fossils, casts, tools, genetics, and changing environments. The Sant Ocean Hall uses a 23,000-square-foot setting, a model of a giant squid, and deep-sea specimens to explain the ocean as a connected living system.
The National Fossil Hall, Deep Time, is built around 4.6 billion years of Earth history and includes The Nation’s T. rex, displayed in a scene of a Cretaceous river ecosystem. In the Janet Annenberg Hooker Hall of Geology, Gems and Minerals, visitors can see the 45.52-carat Hope Diamond alongside meteorites, crystals, and the Dom Pedro Aquamarine. The museum’s 1910 building and long, skylit public spaces are part of the experience, as are changing displays and live interpretations in the Q?rius education area.
- Henry the elephant: The mounted African bush elephant has anchored the Rotunda since 1959 and makes an easy meeting point.
- Hope Diamond: See the famed blue diamond and an exceptional mineral and gem collection in the geology galleries.
- Deep Time: Trace extinction, climate change, evolution, and dinosaur life through fossil specimens and immersive displays.
- David H. Koch Hall of Human Origins: Compare hominin skull casts, examine evidence, and explore what makes humans human.
- Sant Ocean Hall: Encounter marine specimens, coral, ocean science, and a dramatic giant-squid model.

Visiting Tips, Getting There & Nearby Pairings
Arrive close to the 10 a.m. opening, especially on weekends, school breaks, and rainy days, when the Rotunda and gem galleries fill quickly.

Security screening is standard, so allow extra time and travel light.
