History

The Arizona Museum of Natural History was founded as a small museum in Mesa City Hall in 1977 with a small collection of Arizona artifacts, in a building designed by Lescher & Mahoney and built in 1937 with WPA funds, that originally housed Mesa City Hall, municipal courts, city library, police and fire departments. There were expansions to the building in 1983 and 1987, and in 2000 a new wing was added. The main museum complex is currently about 74000 square feet (6,874.8 m²), of which about 46000 square feet (4,273.5 m²) are dedicated to exhibitions containing a collection of about 60,000 objects of natural history, anthropology, history & art, with approximately 10,000 historic photographs. A research facility was also added in 1995. Additionally, the Arizona Museum of Natural History has prominent research curators in the fields of paleontology and archeology/anthropology. Recent annual attendance is about 135,000.
