A temple built on a circular base, possibly consecrated to the Aztec wind god, has been found in the historical centre of Mexico City.

Archaeologist Eduardo Matos Moctezuma told the German Press Agency, Mexico's most respected archaeologist and coordinator since 1978 of excavations on the remnants of the former Aztec capital, said the building was found behind Mexico City's Metropolitan Cathedral.

Experts believe it was consecrated to the Aztec wind god, Ehecatl-Quetzalcoatl, because "such temples had as their characteristic the presence of a circular base and of a square base."

The temple was part of the great Aztec capital, Tenochtitlan, and is believed to have been built in the late 15th century, Matos Moctezuma said.

Its precise dimensions were not known, though the researcher said the structure "could have a diameter of over 30 metres," though excavations were ongoing.
