Mentioned for the first time in 1018, the church, owned by the bishops of Elne, was acquired by count Wilfred II of Cerdanya, who made their capital in the town, in 1025.

In 1094 count William I ordered the construction of a monastery here, which was founded in 1097 and entrusted to the Augustinians.

Until 1167, the priory acquired numerous privileges and possessions, including castles and villages.

The church, in Romanesque style, has a façade in pink marble, surmounted by a tympanum decorated by a Madonna enthroned with Child and Angels.

The circular apse features exteriorly Lombard bands and a sawtooth-shaped frieze, as well as three windows with archivolts over small columns.
