The hermitage of Sant Roc stands on a hill on the outskirts of Massanes, in an open setting that preserves its rural and peaceful character. It is a modest sanctuary but one with a long historical and devotional tradition, especially linked to protection against epidemics.

The building has a single rectangular nave, with a semicircular apse covered by a 15th-century Gothic tradition vault. The roof is a barrel vault with simple eaves and Arabic tile roofing. The façade features a voussoir semicircular arch doorway (currently modified into a flat arch while preserving the original voussoirs), a side window with a grille, an upper oculus and a bell gable, which gives identity to the ensemble. The structure is built in masonry, with partially plastered areas.

The hermitage was authorized in 1569 for the construction of a chapel dedicated to Sant Roc, Sant Jaume and Sant Sebastià, saints protecting against the plague. From the 17th century onwards, a hermit lived there, and by the 18th century it already had two altars. Today, its surroundings have become an open space for social and festive use, where since 1977 a popular rice feast is held every 11 September.
