Located in the historic domain of the County of Ribagorza, the easternmost region of the Aragonese Pyrenees, this village, part of the network of "The Most Beautiful Villages in Spain," stands out as the smallest village in Spain with a cathedral seat. Its Romanesque cathedral is notable for its magnificent cloister filled with funerary slabs and its crypts, which house relics of various saints.

The village's network of narrow streets offers interesting examples of traditional architecture, and being built on a strategic position atop a promontory, it provides spectacular views.
