This 17th-century building was used a century later by the delegate of the Bull of the Holy Crusade and by the preventive offices of the Holy Inquisition. Between 1787 and 1802, it was restored and inhabited by Antonio de Mora y Payzal, who established the Royal Treasury in 1790. In 1856, it came under government control and was used as a school for girls called 'Amiga Nacional,' and later as a school for boys. The building housed the first electric plant. In the early 20th century, Guillermo López Cortés rescued the abandoned building and converted it into the General Archive of the State. In 1971, the project to establish the Rufino Tamayo Museum began, with restoration work overseen by Celestino Gómez Soto. The museum was inaugurated in 1974 with a collection of pre-Hispanic art donated by Rufino Tamayo, originating from Nayarit, Colima, Veracruz, Guerrero, Chiapas, Campeche, and Oaxaca.
