The Museum of the Templo Mayor opened on 12 October 1987. Its creation was the result of the archaeological excavations carried out by the Templo Mayor Project in its first season, between 1978 and 1982, which were made under the direction of Eduardo Matos Moctezuma and allowed to recover a collection of more than 7,000 objects, as well as the vestiges of the Templo Mayor of Tenochtitlan and some surrounding buildings. All this gave rise to the initiative of building a site museum to exhibit the collection and, at the same time, complement the visit of the archaeological area.
