Romanesque church with a single nave, covered by a barrel vault and ending to the east with a semicircular apse. The entrance door, with a semicircular arch and recessed archivolt, opens on the south façade, which also features a simple splayed window. The west façade has a single-eye bell gable, with a monolithic lintel shaped into an arch at the bottom. The walls are built with neatly arranged limestone ashlar blocks. One of the door’s stones bears an inscription dated 1230 in Roman numerals. The parish of Josa is mentioned in the consecration act of La Seu d’Urgell cathedral, drafted in the early 11th century.
