Believed to be the regional capital of the Zoque during the Classic period, these recently opened ruins were inhabited between 250 and 400 AD, and adventurous visitors can visit two restored groupings. The site's most prominent characteristics are its use of megalithic granite architecture, and its most impressive structure, the namesake 'Old Church,' is a 95- by 65-meter pyramid utilizing stone blocks weighing over a ton each. Instead of steps, the apex is reached via a ramp – look for the petroglyph cross at the south side of its base.
The other distinctive feature here is the presence of many carved anthropomorphic and zoomorphic monuments scattered throughout the site. The most well-known are the Sapodrilo (it appears to be a cross between a toad and a crocodile), and the Altar de las Cuatras Caras (Altar of the Four Faces).
