Ancient Aztec palace ruins discovered in Mexico City

Archaeologists have discovered ruins of an ancient Aztec palace, which later became the home of Spanish conquistador Hernan Cortes, in Mexico City. The ruins were found under a historical pawnshop, Nacional Monte de Piedad, which dates back to 1755. Basalt slab floors were found under the building which archaeologists suggest had been an open area in Aztec ruler Axayacatl's palace.
