Teotihuacan (La ciudad donde los hombres se vuelven dioses/place where men become gods)
Pirámide del Sol/Pyramid of the Sun
Is the second largest in the continent, 60m high and 260m by side. Some parts has been rebuilt so its not the original look. Is also oriented to the west where sun "dies". Under the structure is a cave with 4 tunnels, meaning the directions of the universe, maybe that's the reason why it was erected here.
