In the old county of Ribagorza, one of the original counties from the Crown of Aragon, and very close to the Isabena river, Roda de Isabena was erected.
Roda de Isabena can boast of being the smallest town in Spain to have a cathedral. The cathedral, destroyed in the late 10th century, was rebuilt between 1053 and 1067, and continued to be remodelled in the 12th century. There we can admire the cloister, the sarcophagus of San Ramón and the High Reredos. The old refectory was turned into the restaurant of the hostel that is now located there. Visitors are surprised that such a small town could house an Episcopal See of such great importance during its time, and still in our days, as it is considered to be a site of great artistic and historical interest. Only when we consider the historical context of the 10th century, with the creation of resistance groups to fight off the Arabs in the area of the Pyrenees, can we understand the reason why the cathedral was built. From this town we can take excursions to the nearby valleys of Bisecas and Ventanillo.
