These pre-Inca faces are no laughing matter. They congregate on rocks leading up to a ceremonial site overlooking the town of Quila Quila near Sucre. The locals won't go up there, as the carvings of knives and alienlike creatures with antennae understandably give them the heebie-jeebies.

It is generally agreed that this was a place of human sacrifices though there is absolutely no written history to back this up. What is known is that in the same valley there was an enormous battle between the Spanish invaders and the Indians. The Indians lost of course, but they left behind a lot of little stone arrowheads which glint from the edge of the road from time to time.
