Hundreds of people celebrated the spring equinox on Wednesday with a visit to the Teotihuacan archaeological site outside of Mexico City.

Tourists visited the Temple of the Moon and the Temple of the Sun to welcome the beginning of spring, many of them dressed in white and red.

Technically, the equinox occurs when the sun comes in alignment with the equator.

These are colours that according to pre-Hispanic tradition help to better absorb the good energy that peaks during the equinox.

At the base of the temples, traditional medicine practitioners performed ritualistic cleansings on tourists.

A popular tourist site about an hour's drive north of Mexico City, the massive pyramids at Teotihuacan were built by a relatively little-known culture that reached its height between 100 BC and AD 750.

The site was abandoned by the time the Aztecs arrived in the area in the 1300s and gave it its current name.

Teotihuacan is located 48 kilometres northeast of Mexico City and it is visited by over three million tourists every year.
