Mexico, Chichen-Itza, "Stadium" to Play Ball - Gran Juego de Pelota

The great ball court, the largest and most impressive in Mexico. The court is bounded by towering parallel walls with stone rings cemented up high.
It is thought that they played a soccer-like game with a hard rubber ball, with the use of hands forbidden. It appears that if a player hit the ball through one of the stone hoops, his team was declared the winner.
The court exhibits some interesting acoustics: a conversation at one end can be heard 135m away at the other, and a clap produces multiple loud echoes.
