Loosely translated, tierradentro means "within the ground." Within the ground here you'll find the New World's largest concentration of hypogea, or underground burial chanbers, constructed much like Rome's catacombs. The name of the pre-Columbian people who constructed the tombs has been lost. Most are thought to date from the 6th through 10th centuries. Many of the tombs—78 have been excavated so far—are up to 40 feet wide with walls painted with anthropomorphic
and zoomorphic figures. Tierradentro is a bit harder to reach than San Agustín and Alto de las Piedras parks; as with the other parks, a guide is useful to help you understand what you're seeing here.
