National Palace, Mexico City, Distrito Federal, 17th Century
Well before the Conquest, the Aztecs built the \"New Houses\" of the Emperor Montezuma on the central plaza of Tenochtitlán. When the Spaniards occupied the city, they razed the home of the former emperor. Hernán Cortés then built his palace on these pre-Hispanic foundations using the stones of the former buildings. A century later Cortés\' Palace burned down. Friar Diego Valverde started reconstruction of the palace in the late 1620\'s. Renovations continued into the 20th Century, and in 1926, a third story was added to the existing building.
