The hermitage of Mare de Déu de la Pertusa is a religious building in Romanesque style located in one of the most valued and beloved spots to enjoy the landscape of the Montsec mountain range. This construction is situated on a rocky relief and provides an exceptional viewpoint over the Canelles reservoir and the Montsec d'Ares and Montsec d'Estall mountain ranges.

It is a building constructed in a spectacular location and only accessible from the north side, as the south side directly faces a cliff. The small church, documented since 1162, consists of a single nave with apse and an exterior roof made of slabs. It is fairly well preserved.
