Arles was an archbishopric from the 4th century until 1790, and this Romanesque-style church was once a cathedral. Built in the late 11th and 12th centuries, it’s named after St Trophime, an Arles bishop from the 2nd or 3rd century AD. On the western portal, the intricately sculpted tympanum depicts St Trophime holding a spiral staff. Inside, the treasury contains bone fragments of Arles’ bishops. Occasional exhibitions are hosted in neighbouring cloister, Cloître St-Trophime .
