Pyramid of the Niches, El Tajín
This unique and intricate little pyramid is located in El Tajin, on the central Gulf coast in Veracruz. Its builders are mysterious and may have been either Totonac or Huasteca. El Tajin flourished at the same time as the Maya, and there is evidence that the builders of El Tajin and the Maya had a trade relationship. The pyramid has 365 niches, representing the solar year, and is almost perfectly symmetrical.
