James Mitchell Museum, Geological museum at University of Galway, Ireland

The James Mitchell Museum is located on the university campus and holds a collection of fossils and mineral specimens from different parts of the world. The objects are arranged in period cabinets within the Quadrangle building.

The museum was founded in 1852 on the collections of William King, whose original catalogues survive. In 1883 Richard J. Anderson merged the geology and zoology collections into a Natural History Museum; under Henry Cronshaw it was broken up and only the geological collections stayed. James Mitchell held the Chair of Geology and Mineralogy from 1921 to 1966, and the museum was named after him in 1977.

The museum's Victorian cabinet display, likened to a "museum of a museum", keeps the original arrangement of the geological collection. The name honours Professor James Mitchell, who held the Chair of Geology and Mineralogy from 1921 to 1966. The original catalogues compiled by William King are still extant.

The museum is located in a specific area of the university grounds and is not always open for casual visits. Visitors should contact in advance and arrange a time to come.

The collection includes remains of ancient sea reptiles from millions of years ago and preserved plant impressions from the region. These rare pieces come from locations famous for their fossil discoveries.
