Ermita de la Pietat, Hermitage church in Ulldecona, Spain

La Pietat is a sanctuary and hermitage built against the walls of the Mola de Godall, about 4 km north of Ulldecona. The complex consists of a church and a hostel facing each other, linked by a two-storey porch whose upper level has a gallery of round arches. The church has a single rectangular nave with a barrel vault and a polygonal apse with ribbed vaulting; the hostelry preserves structures of 13th-century Romanesque and 14th–15th-century Gothic chapels.

No documents predate the 15th century, though a chapel may have followed the Reconquest. The first known reference is a 1445 pilgrimage decreed by Tortosa's council to pray for rain in a drought. The first floor of the body between hostelry and church was built in 1687, its date carved on a door lintel, and the confraternity of Nostra Senyora de la Pietat was founded in 1689. The sanctuary stayed closed from 1810 to 1812; in 1936 anarchists burned the church, destroying the altar, retables and choir, and reconstruction began in 1939.

The name Pietat refers to the Virgin of Mercy venerated in the sanctuary. The Confraternity of Nostra Senyora de la Pietat was founded in 1689, and the altar was gilded in 1779. A document of 1445 records a pilgrimage decided by the council of Tortosa to ask for rain during a drought, the first known reference to the site.

The sanctuary lies about 4 km north of Ulldecona, reached by the traditional Camí de l'Ermita that skirts the Serra de l'Ermita, or by the road linking the hermitage to the Tortosa road. A small chapel at the Tortosa road marks the start of the path. A masonry wall about 2.5 m high encloses the precinct, with a broad esplanade outside used as parking.

Nearby sits the Abric d'Ermites cave, which holds prehistoric paintings recognized as a UNESCO World Heritage site. These artistic works reveal human activity from thousands of years before the hermitage was built.
