The modern Zócalo in Mexico City is 57,600 m2 (240 m × 240 m). It is bordered by the *Mexico City Metropolitan Cathedral (map) to the north, the National Palace (map) to the east, the Federal District buildings to the south and the Old Portal de Mercaderes to the west, the Nacional Monte de Piedad building at the north-west corner, with the *Templo Mayor site (map) to the northeast, just outside view.
In the centre is a flagpole with an enormous Mexican flag ceremoniously raised and lowered each day and carried into the National Palace. There is an entrance to the Metro station “Zócalo/Tenochtitlan” located at the north-east corner of the square but no sign above ground indicates its presence.
Prior to the conquest, the area that the Zócalo occupies was open space, in the center of the Aztec capital Tenochtitlan. It was bordered to the east by Moctezuma II’s “New Houses” or Palace (which would become the National Palace) and to the west by the “Old Houses”, the palace of Axayacatl (1469–1481) where the Emperor Ahuitzotl, Moctezuma’s uncle and immediate predecessor also lived.
