Mitla

Zapotec groups settled here by about 200 CE, in the upper Tlacolula valley. As Monte Albán declined in the 9th century, Mitla grew into the leading religious center of the region, and it reached its height around 1200 CE.

By then Mixtec people had a strong presence in the valleys, and their hand shows in the architecture and the painted friezes. Mitla held its authority over the Tlacolula valley until the Spanish arrived in the 1520s.

The surviving monuments are laid out in five groups, most built as pairs of courtyards ringed by long halls. The finest is the Group of the Columns, named for the row of monolithic stone pillars in its main hall.

Every wall is faced with grecas, geometric fretwork assembled from thousands of small cut stones set into the masonry without mortar. The pieces hold by fit alone, and no panel repeats another exactly. Mitla is often described as the only place in Mesoamerica where this mosaic covers whole facades rather than a single decorative band.

The names say it plainly. In Nahuatl the site is Mictlan, the place of the dead, and in Zapotec it is Lyobaa, the resting place. Mitla was a burial ground for rulers, nobles, and high priests, with cruciform tombs cut beneath the palaces.

According to tradition, the caverns under the site opened onto the underworld, tended by a high priest the Zapotec regarded as a mouth of the gods. People came here to bury their dead and, the accounts hold, to sit closer to the world below.

In the 16th century the Spanish raised the church of San Pablo on top of a pre-Hispanic platform, reusing the ancient stone. The colonial sanctuary and the Zapotec mosaics now stand side by side, one built to bury the other.

In 1674 the Dominican friar Francisco de Burgoa wrote that missionaries had entered a vast underground chamber below the site and, disturbed by it, ordered the entrance walled up. In 2022 a team using ground penetrating radar and other scans, the Lyobaa Project, mapped real voids and passages beneath the church, matching the old descriptions.

Mitla is an easy day trip from Oaxaca, often paired with the petrified falls at Hierve el Agua and the weaving town of Teotitlán del Valle. The archaeological zone sits within the modern town of San Pablo Villa de Mitla, still Zapotec-speaking and known for its textiles and mezcal.

You can walk right up to the fretwork and into the courtyards, which makes the craftsmanship easy to read up close. This is a cemetery as much as a monument, so it rewards a slow, quiet visit.
