The Museum of Natural History was originally located in the center of the Natural History Building, occupying a respectable 51 by 63 foot space.  It later moved to quarters on the fourth floor until around 2001, when it was closed and its more than 420,000 artifacts  moved to the new Spurlock Museum. Among this spectacular assemblage is the entire bird collection from the Columbian Exposition of the 1893 Chicago Worlds Fair.
