I’m having some trouble getting my Maya materials online because there are so many of them, and there’s just so little time. So, we’ll do this one building at a time. This is “El Caracol” (“the snail,” so called in Spanish for its winding internal staircase), which is called “The Observatory” in English.
It’s not hard to see how it gets that name, because it looks a lot like a modern observatory. It’s quite unusual for a Maya building, with its round dome placed on a square base. Slits in the dome allowed viewing the sky at the cardinal and subcardinal directions. Certainly the movements of celestial objects were important to the Maya, and their astronomical reckoning was quite advanced (witness their highly accurate calendar). But I’m not sure that we can say definitively how this building was used in its particulars. As with all Maya sites, a great deal of fancy has come to surround the ruins, making it difficult to separate fancy from fact.
The earliest parts of the Observatory were probably constructed in the ninth century. The building underwent several modifications over the succeeding centuries.
