Trinity Chapel is one of two churches that stand on the Ville Close island in the heart of old Concarneau. It is noted because of the unusual architectural style that is built in, quite representative of the Breton school of the Middle Ages. The beautiful church is no longer used as a place of worship, and due to the large demand for entertainment from the many visitors to the town, it is now a busy and interesting theatre, showing a variety of acts throughout the year.
