National Museum of Natural History

Across the Mall from the Smithsonian Castle, and just before the American History Museum is the Smithsonian Natural History Museum.

Delve into the fascinating story of our planet from its fiery beginnings four and a half billion years ago, and explore all the exhibitions and activities.

The museum's collection contains more than 145 million specimens of plants, animals, fossils, minerals, rocks, meteorites, and human cultural artifacts.

And don't forget to visit the beautiful Hope Diamond!
