With more than 120 million objects in its research collections, the museum is a fascinating resource on people and their natural surroundings.
Visitors can learn about humanity's earliest history and the development of world cultures.
Thousands of specimens of mammals, birds, amphibians, reptiles, insects, sea life, fossils, gems, minerals, rocks, ores and meteorites are on view. Parking On Madison Drive, there are three parking spaces at the east end of the museum and two parking spaces in front of the museum for people with disabilities. However, the National Mall entrance, from Madison Drive, is not accessible. Visitors using wheelchairs must go around the building to the Constitution Avenue entrance, located on the north side of the building. The District of Columbia has not designated any parking spaces on Constitution Avenue for people with disabilities.
