The parish church has a Romanesque chevet and a square tower for defensive purposes.

The Romanesque porch was decorated with a Chrism, the symbol of the Holy Trinity. This tympanum is now re-used in the south doorway and there is a second Chrism on the wall of the bell tower.

The church was dedicated to Saint Catherine until the 18th century. At that time, the construction of an altarpiece in praise of the Assumption of the Virgin consecrated it to Notre-Dame. The statue of Saint Exupère, taken from the old altarpiece, was made by the Ferrère workshop.

The church's interior was decorated under the direction of Pierre Minvielle, a sculptor and gilder from Bagnères de Bigorre. Numerous alterations have been made over the years.

In 1844, a monumental portal was opened in the bell tower, based on a plan by the surveyor Verdier d'Arreau.

The church houses a splendid 16th-century Pieta. It was on the reliquary arm of Saint Exupère that the Consuls and Syndics of the Vallée d'Aure took their oath every year.
