The University of Arizona Alfie Norville Gem & Mineral Museum is located in the Pima County Historic Courthouse in downtown Tucson. Since its inception in 1918, the museum has housed a variety of mining and mineral related collections. The museum has changed location several times, moving from the Flandrau Science Center and Planetarium to its present location when renovations of the courthouse were completed in 2021.
