Cenote at Bolonchen used as source of water, 1842.

The large Bolonchén ruins site of ancient Maya architecture is located just north of the modern town. It dates from the Mayan Classic Period and Post Classic Period. Most of the carved stone facades of the ancient structures were removed in the 18th through mid−20th centuries for reuse in new construction work. Nonetheless, a few monuments with sculpture and hieroglyphic texts are still visible.
