Tingambato — sometimes called Tinganio — is a modest, well-kept set of ruins on the southern edge of the village, occupied from roughly 450 to 900 CE and showing clear architectural influence from Teotihuacán far to the north. The site spans about 50 hectares but only a small core has been excavated: two plazas, a stepped pyramid, a sunken patio with talud-tablero walls, and a Mesoamerican ball court that is among the few examples of its kind found in western Mexico.
The on-site tomb, discovered in 1978 and reopened by INAH archaeologists in the 2010s, is the highlight. A narrow staircase descends into a chamber that held thirty-two individuals and an extraordinary array of grave goods. The most spectacular finds are now in museums in Morelia and Mexico City, but the chamber itself can still be visited. The small museum at the entrance houses ceramics, obsidian blades, and a few of the smaller objects from the original excavations.
The site is open daily, charges a small INAH entrance fee, and is rarely busy — you may have it to yourself. Allow about an hour. Combine with a stop in Pátzcuaro or Uruapan, both within easy driving distance.
