|The Pyramids of the Sun and the Moon|
This building is not found within the circuit of the current tour, but the Pyramids of the Sun and the Moon Archaeological Project plans to include it beginning in 2011. Although this building has been investigated little, it is believed to have played a more civil-administrative than religious role.
When the Old Temple was in active use, the Pyramid of the Sun was just a small building, but after the abandonment of the old temple, an architectural project of Pharaonic levels began to build the monumental structure that we can still appreciate today.
This structure is easily visible from a distance due to its spectacular size, being one of the largest adobe structures of pre-Hispanic America. Its possible dimensions were 345 meters long by 160 meters wide and30 meters high. Unfortunately, it was greatly damaged by treasure hunters in the seventeenth century, leaving only one third of its original structure intact.
