The church is in the Gothic style typical of the Languedoc region of France, with a single nave and chapels located between buttresses. The first arch rests on capitals of clear Muslim origin. It was declared a National Monument in 1943 thanks to the intervention of Elías Tormo.

Since 1987, the church has been being restored and returned to its primitive Gothic style. Any baroque decoration that it had was removed, leaving only the chapel of Santa Bárbara, with its sgraffito from the end of the 17th century.

The paintings in the chapels, which appeared after the restoration of the church, are from the 13th century. The church was covered with lime on the inside since the 14th century, this has made the paintings very well preserved.
