This very small archaeological site, 1km northeast of central Cuernavaca, actually has two pyramids, one inside the other. You can climb on the outer base and see the older pyramid within, with a double staircase leading up to the remains of a pair of temples. Tlahuicas built the older pyramid over 800 years ago; the outside one was being constructed by the Aztecs when Cortés arrived, and was never completed. The name Teopanzolco means "Place of the Old Temple."
There are a few explanatory signs in English. The site was damaged by the earthquake of September 19, 2017. At the time of writing it was closed for restoration work even years later.
A surprising result of the tremors was the discovery of the remains of an even older Tlahuica temple inside the pyramids dating back to 1150, dedicated to the rain god Tláloc with an accompanying incense burner. Check before your visit to ensure that the site has opened again.
