Tecozautla

One of only 5 sites known to have been used by the Xajay culture, a little known indigenous group who were evidently related to the Otomi and who paid tribute to Teotihuacan. The biggest building at Pahnu is the Pyramid of Xiuhtecuhtli. It's fairly large, but it won't impress you if you've been to big sites like Teotihuacan. However, while many Mexican archaeological sites have been closing off structures so visitors could no longer climb them, visitors can still climb the steps of Pyramid of Xihtecuhtli and admire the panoramic vistas of the arid valley. A small site museum displays relics from the site.
