Overview

The Olmec heartland is the area in the Gulf lowlands where it expanded after early development in Soconusco, Veracruz. This area is characterized by swampy lowlands punctuated by low hills, ridges, and volcanoes. The Sierra de los Tuxtlas rises sharply in the north, along the Gulf of Mexico's Bay of Campeche. Here, the Olmec constructed permanent city-temple complexes at San Lorenzo Tenochtitlán, La Venta, Tres Zapotes, and Laguna de los Cerros. In this region, the first Mesoamerican civilization emerged and reigned from c. 1400–400 BCE.
