Coba archaeological site, 77793 Q.R., Mexico
Next to Nohoch-Mul is a beautifully restored conical structure that archaeologists have named Xaybe, which in the Yucatec Maya language means "crossroad," due to the fact that sacbe 1, 5, 6, and 8 converge near the building. For the same reason, archaeologists believe it may have served as a watchtower. Nevertheless, its unique design and impressive size suggest a more significant purpose. Round structures are quite rare in Maya architecture, and most of them are considered astronomical observatories; however, there is no evidence that Xaybe served this function, especially since it lacks any upper platform or temple.
The building dates to the Classic period; it is a four-tiered conical structure with two central moldings. It has a base divided into two parts: one of normal size, later, which initially reaches the second tier, and the original one, visible from it, but due to its proportions, it is unlikely to have served this function. There is a staircase on the western side of the structure. In front of the staircase is a covered stela.
It is from the Xaybe plaza, from the southwest corner heading west to Yaxuná, that the sacbe 1 leads—a 100 km long causeway, the longest Maya sacbe in the world.
