The parish church of Trouville sits a few streets back from the harbour, behind the older part of town. It's a 19th-century Romanesque Revival building with a tall stone tower visible from the quayside, the work of architect Pierre-Louis Bouvier and dedicated in 1875.
The interior is plain compared to medieval Normandy churches, but the stained glass and the open wooden roof are worth a short stop. The square in front is a small piece of village France in the middle of the resort town.
