A carbon sample from a burned area of the Structure C-1’s surface resulted in the date of 394 ± 30 BCE.One of the earliest pyramids known in Mesoamerica, the Great Pyramid is 110 ft (34 m) high and contains an estimated 100,000 cubic meters of earth fill.La Venta is a pre-Columbian archaeological site of the Olmec civilization located in the present-day Mexican state of Tabasco.Some of the artifacts have been moved to the museum "Parque - Museo de La Venta", which is in nearby Villahermosa, the capital of Tabasco.Unlike later Maya or Aztec cities, La Venta was built from earth and clay—there was little locally abundant stone for the construction.Large basalt stones were brought in from the Tuxtla Mountains, but these were used nearly exclusively for monuments including the colossal heads, the "altars" (actually thrones), and various stelae.
It is assumed that many of these platforms were once topped with wooden structures, which have long since disappeared.
Roughly 200 kilometres (124 mi) long and 80 kilometres (50 mi) wide, with the Coatzalcoalcos River system running through the middle, the heartland is home to the major Olmec sites of La Venta, San Lorenzo Tenochtitlán, Laguna de los Cerros, and Tres Zapotes.
By no later than 1200 BCE, San Lorenzo had emerged as the most prominent Olmec center.
The Olmec was one of the first civilizations to develop in the Americas.
Chronologically, the history of the Olmecs can be divided into the Early Formative (1800-900 BCE), Middle Formative (900-400 BCE) and Late Formative (400 BCE-200AD).The humid tropical climate of La Venta has an average annual temperature of 26 degrees Celsius and an average annual rainfall of 2,000 millimeters.
