The Huastec civilization is a pre-Columbian Mesoamerican culture that occupied an area along the coast of the Gulf of Mexico, which included the northern part of the state of Veracruz and the neighboring regions of the states of Hidalgo, Queretaro, San Luis Potosi and Tamaulipas.

Huastecs often built round mounds in major urban centers. The diameter of one of the mounds found is 20 meters, it was built from limestone and basalt, which are believed to have been brought from afar.

It contained the remains of three adults, as well as flower-shaped shell jewelry, obsidian blades, and green quartz earrings..

The diameter of another burial mound is 30 meters; the remains of an adult were found in it, placed inside a limestone structure.. Similar burial practices have been observed in other regions where Huastec burials have been found..
