What Archaeology Says

A major Maya city that reached its height between 600–1200 AD. El Castillo (Temple of Kukulkan) is a solar calendar — its stepped sides count the 365 days of the year. The serpent shadow effect during equinoxes is a real astronomical alignment intentionally designed by Maya architects. The acoustic echo is a well-documented architectural phenomenon.
