A museum with the charm of times past. The original cabinets exhibit collections of minerals fossils and even meteroites, specimens of fauna and flora of the various regions and, last but not least, a series of landscape paintings by José María Velasco. In the main room the impressive skeleton of a mammoth is displayed. It is a reconstruction was achieved using the bones of 12 mammoths from across the country.

In addition to the geological richness, its stone facade has reliefs depicting fossil shells, reptiles and ammonites under the three arches of the entrance. The building is reminiscent of French Art Nouveau style, a place to learn and be surprised. It is currently run by the National Autonomous University of Mexico.
