The History of the Museum

Tracing its roots back to the founding of the institution, the museum’s collection was initially housed in the Smithsonian Castle. Then known as the National Museum Building, the Arts and Industries Building was constructed in 1881 to house the institution’s growing number of exhibits. As the collection outgrew its second home, building, Congress authorized the construction of a larger structure. Opening in 1910, it was the first Neoclassical-style building to be erected on the north side of the National Mall. The building’s green dome is an iconic landmark along the Mall.

Inside the Museum

Henry, the museum’s iconic 14-foot-tall, 12-ton African elephant that made its debut in 1959, greets visitors in the rotunda. A recent renovation of the rotunda revealed a once hidden compass inlaid in the floor.

In addition to the Hope Diamond, the Janet Annenberg Hooker Hall of Geology, Gems and Minerals also displays the Star of Asia Sapphire and the Gachala Emerald as well as an extensive collection of meteorites.

The David H. Koch Hall of Human Origins opened on the 100th anniversary of the current building. The exhibits chronicle the primordial record of human life on the planet. The primary exhibit focuses on the aspects that make humans unique. Topics include the size of the brain as well as the ability to walk upright and to use complex verbal and nonverbal communication. The highlight of the hall is an authentic Neanderthal fossil.

The Hall of Dinosaurs and Paleobiology, featuring a collection of 46 complete dinosaur specimens, reconstruct the history and behavior of these extinct creatures. The gallery also documents the region’s ancient climate and terrain that served as the natural habitat for these massive animals. Highlights include complete skeletons of a T-Rex, a megacerops and a triceratops.

Visitors to the National Museum of Natural History can learn about various creatures that have resided on the planet in galleries dedicated to mammals, insects and the world’s oceans. The museum has the largest collection of vertebrate specimens that trace the adaptations of mammals to their diverse and changing surroundings. Highlights include the lion and polar bear exhibits. The Orkin Insect Zoo reveals how various types of insects thrive in different environments, such as rain forests, swamps and deserts. Children will enjoy watching the live tarantula feedings. The Sant Ocean Hall highlights the biodiverse world that exists beneath the waves. The 1,500-gallon aquarium features a live tropical Pacific coral reef and a giant squid. The Butterfly and Plants pavilion enables visitors to observe the symbiotic relationship between plants and these colorful creatures.

The cultural history of humans is also on display. Exhibits trace the development of western civilization from ancient Mesopotamia, Egypt and Greece as well as the unique cultures and traditions of Africa and Asia. In addition to seeing how people live and work in their natural surroundings, you will see how they affect these environments. One example of this dynamic relationship is the mud masons of Mali who built Djenne, a UNESCO World Heritage Site known for its intricate earthen architecture.

Q?rius is the museum’s education center where teens and preteens can get hands-on experience working in a lab and making their own scientific discoveries. The Johnson IMAX Theater shows feature-length nature films in 3D. Performances sellout early, so purchase your tickets when you first arrive at the museum. The facility also hosts sleepovers for children ages 8 to 12 years old.
