Diego Rivera Mural at Cortez Palace - The Palacio de Cortés is considered to be the most representative building of Cuernavaca and one of the oldest European style buildings in the Americas. The series of arches of the central terrace and the thick walls are the most representative aspects of the original construction. Just outside the front of the building is an old pyramid base over which Cortés had the structure built. After having been the residence of Cortés and his descendants for several centuries, the building became a warehouse, a jail, a military barracks, and then the State Government Palace. In 1973 the building was restored and today houses the Museo Regional Cuauhnáhuac, dedicated to the history of Morelos State with famous murals by Diego Rivera.
