All of the 17 known Olmec colossal heads discovered so far. The heads date from at least 900 BCE, and it is thought that they represent portraits of powerful individual Olmec rulers. The head, in the 1st picture, is the largest of them all, measuring 3.4 m in height and weighs 40 tons [2205×2538]

All of the 17 confirmed Olmec colossal heads are located in Mexico.

There’s also a monument in Takalik Abaj in Guatemala that could possibly be another Olmec head, but archaeologists are still not sure.

> Takalik Abaj Monument 23 dates to the Middle Preclassic period, and is found in Takalik Abaj, an important city in the foothills of the Guatemalan Pacific coast, in the modern department of Retalhuleu. It appears to be an Olmec-style colossal head re-carved into a niche figure sculpture. If originally a colossal head then it would be the only known example from outside the Olmec heartland.
