17th-century building, attributed to master builder Joseph Eduardo de Herrera, who inherited and converted the estate into a residence. In 1847, after the Battle of Padierna, the South Carolina Battalion of the U.S. Army occupied the building for several months, housing over 700 men. Its last owner, politician Isidro Fabela Alfaro, donated it to the people of Mexico along with the Historical Archive in October 1958. Between 1963 and 1988, it operated as a site museum, and in June 1991, it reopened with a new museography.
