Hernán Cortéz destroyed the aqueducts in 1521 to cut off the enemy's water supply. A castle was built in 1787 to house the leadership but remained empty until 1841. The castle was nearly destroyed in the US invasion of 1847. The Monumento a los Niños Héroes commemorates the cadets whose defense cost them their lives. In 1864 Maximilian von Habsburg made the castle his imperial residence. With the re-establishment of the republic, the castle was appointed the seat of the president, but Porfirio Díaz was the first to take residence in 1876. Ultimately it was designated the Museo Nacional de Historia in 1944.
