Built in the 12th-13th centuries, the church was originally the castle chapel. Richard C?ur de Lion's entrails are said to be buried here. The porch of the gateway to the castle courtyard, the triumphal arch separating the nave from the choir, and a niche with an accolade in the chapel all remain. A capital from the Romanesque choir is still in situ. Fragments of columns, capitals and statue supports are housed in the château.
