Nothing remains of the primitive Romanesque church and the 13th century church. The present church dates partly from 1628, and retains the Romanesque layout and a portal that copies the Romanesque style. The history of the chapel of Montgauzy is eclectic. Its foundation commemorates the victory of Charlemagne over the Moors in 778, and the chapel then became a place of pilgrimage. In 1340, the Bishop of Pamiers, Arnaud Villemur, had to intervene against the bad behaviour of some of the increasing numbers of pilgrims (there were reports of noisy evening events). On 4 January 1562 the chapel was one of the many targets of the Reformation, and in 1579 the governor of the castle of Foix demolished it. It was rebuilt in 1628 and pilgrimages recommenced. Following the revolution, having been rebuilt, it was sold in 1791. This, now private, property fell into ruin due to lack of maintenance. It was then purchased by the department in 1840. An École Normale was established in the area and, in 1843, the chapel was once more made fit for worship. It was closed again in 1883, and the furniture was scattered. After repairs in 1943, it was again reopened for worship.
