The history of Alquézar is deeply linked to its strategic location above the Vero River canyon. It was founded as an Islamic fortress to control access to Barbastro and the Ebro Valley, and reconquered by Sancho Ramírez in the 11th century. From then on, the fortress was transformed into a Christian collegiate church, and the town center began to grow around it.
For centuries, Alquézar prospered as a transit point, agricultural village, and religious center. The narrow cobblestone streets, stone houses with wrought-iron balconies, and vaulted passageways are a direct legacy of that era. Today, the layout of the town has barely changed, making it a true historical treasure.
