Cholula, just off Highway 190 about 18 miles beyond San Martin Texmelucan, is a town of churches. Here, as elsewhere, the Spaniards built churches over structures sacred to the Indians. You can visit some 39 chapels in close proximity, and many more are not far away. Most notable is the Sanctuary of Los Remedios because it was built atop Cholula's main pyramid, a mile in circurnference at its base. Not a true pyramid but an acropolis composed of numerous structures, it was fashioned over a period of several centuries beginning about 100 A.D. Tunnels allow you to explore some sections.
The ancient city has been under study and restoration for many years. A museum at the excavation site houses a collection of fabulous Cholulteca pottery, a polychrome lacquer-type ware decorated with intricate designs.
Cholula is also the location of an impressive new campus of the University of the Americas that moved here from its outgrown facility on the western edge of Mexico City.
