A day of awesome Mayan history from their mastery of mathematics and astronomy through to rituals, games and human sacrifice.

If you stand at the foot of Chichen Itza and clap your hands a really neat acoustic effect happens as the sound echos up the pyramid and gets repeated back to you the sound transforms and mimics the call of the Quetzal bird.

The Mayans regarded it a great honor to be sacrificed to the gods. One of the pictures below shows skull carvings of the Mayan Ball game players who were sacrificed by decapitation for winning the games (Games happened once every 52 years).
