The National Museum of Natural History welcomes approximately seven million visitors a year. With its unparalleled collections and exhibitions – and its monumental architecture – it is also a premiere site for after-hours special events. The grand, four-story Rotunda can accommodate seated dinners for up to 350, or standing receptions of up to 500. When the Rotunda is combined with adjoining exhibition halls, guest capacity may increase to as many as 2,500. The Sant Ocean Hall, Behring Family Hall of Mammals, Dinosaur Hall, and the Hooker Hall of Geology, Gems and Minerals are all popular venues. Smaller seated dinners can be hosted around the Hope Diamond or under the North Atlantic Right Whale. A live butterfly pavilion and changing photography shows related to nature are also available, as well as the Johnson IMAX® Theater and the 565-seat Baird Auditorium.
