One of the largest natural history museums in the U.S., the Fernbank's architecture is as intriguing as the fascinating exhibits inside. The building has spiraling staircases, huge columns, a brick atrium and windows looking out onto the forest that it borders. The exhibits are spectacular and include a life-sized kaleidoscope, a skeleton of the largest dinosaur ever discovered, an IMAX theater and a "Walk Through Time in Georgia," a story of the earth's develoment, complete with sound effects and recreated landscapes of a swamp, cavern, marsh and plateau.
