# Xpuhil

> Xpuhil Pronounced:/ʃpuχil̥/ (also Xpujil) is a Maya archaeological site located in the Mexican state of Campeche, in the vicinity of the modern-day town of Xpujil. The area surrounding Xpuhil, along Federal Highway 186, is rich with other Maya sites, including Becan and Calakmul. The name xpuhil means "cat's tail" in reference to a type of vegetation found locally [Wikipedia](https://en.wikipedia.org/wiki/Xpuhil)
