Becán ruins are about 7 km (4 mi.) w. of Xpujil on the n. side of the highway and can be reached via a short road (watch for the turn-off sign). Surrounded by a dry moat that probably was used as a fortification (the name means “ravine formed by water”), the site once was accessed by seven causeway bridges. This is the most developed of the Río Bec sites and has some of the largest structures, including a twin-towered temple (Structure IX), plazas surrounded by low-rise buildings and a ball court. There also is a nicely preserved stucco mask on display (behind glass) at Structure X.
