A giant temple to the Aztec god of the wind and a court where the Aztecs played a deadly ball game have been discovered in the heart of Mexico City.

Archaeologists unveiled the rare finds on Wednesday after extensive excavations, giving journalists a tour of the semi-circular temple of Ehecatl-Quetzalcoatl and nearby ball court.

Records indicate that Spanish conquistador Hernan Cortes first watched the ritual Aztec ball game at the court in 1528, invited by the last Aztec emperor, Montezuma - the man whose empire he went on to conquer.
