A fortified hilltop city built by Matlatzinca and Otomi groups starting around 900 CE and later incorporated into the Aztec Empire, with restored plazas, ballcourts, and defensive walls overlooking the Toluca Valley.
Teotenango was founded around 900 CE by Matlatzinca and Otomi groups on a defensible hilltop above the modern town of Tenango del Valle, and it grew into the fortified capital of the Matlatzinca kingdom before being conquered and incorporated into the Aztec Empire under Axayacatl around 1476 CE. The city's name, given by the later Nahua occupants, means 'place of the walled city,' referring to the defensive stone walls that still enclose sections of the site. Excavated and restored areas include multiple sunken plazas, a Mesoamerican ballcourt, temple platforms, and residential terraces laid out to follow the hill's natural contours, reflecting a settlement pattern built for defense as much as ceremony. Archaeological work beginning in the 1970s uncovered stone sculpture, ceramics, and architectural remains spanning both the Matlatzinca and later Aztec occupation phases, and the site's on-site museum displays artifacts recovered during these excavations. Teotenango's elevated, walled position overlooking the Toluca Valley made it a strategic stronghold controlling trade and movement through the valley, and the site remains one of the largest fortified hilltop settlements documented in the central Mexican highlands. Conservation and consolidation of the exposed plazas and walls have continued intermittently since the initial excavations, and admission to the site remains free.
Why it matters
Teotenango was the fortified capital of the Matlatzinca kingdom before its conquest by the Aztec Empire, and its extensive defensive walls make it one of the best-preserved examples of a walled hilltop city in the central Mexican highlands.

Tips for visiting
- Wear closed-toe shoes for the uneven hilltop terrain and bring water, since there is little shade on the open plazas.
