You'll find the National Museum of the American Indian on the National Mall. Its structure is a throwback to adobe homes in early Native American culture. With a highly naturalistic design, the NMAI illustrates Native American history within a series of circles. Various works of art, artifacts, and other remnants of American Indian culture are on display. Changing exhibits provide a valuable addition to our understanding of American Indian culture. Past exhibits have included indigenous world views through dress, native modernism, and contemporary indigenous viewpoints as told through poetry. Admission to the museum is free. It is, however, recommended that a timed entry pass be reserved online (with a service charge) because of the popularity of this national exhibit.
