And the neat structure at the end of the ball court at Chichen Itza. The court is the largest so far discovered, and it is indeed huge! I have absolutely no idea how anyone could manage to play anything, let alone anything like the descriptions thus far offered for the ancient Mayan game, on a field that huge, especially without shade and in the heat.
We also visited (but alas, did not swim in) the sacred cenote, or sinkhole. The huge sinkholes in the local limestone often hold a lot of fresh water. The Mayans threw offerings to the gods into this one, though not into all cenotes.
