Chapelle Notre-Dame-de-Pitié de Trouville-sur-Mer, Religious chapel in Trouville-sur-Mer, France.

The Chapelle Notre-Dame-de-Pitié de Trouville-sur-Mer is a private chapel of 30 m² on a 85 m² plot at 34 rue de la Chapelle in the Bonsecours district. Its steep gabled facade mixes red brick and pale stone, with a double wooden door under a round-headed fanlight arch, a small statue in a niche above, and a square open wooden bellcote with a pyramidal roof at the top.

The Surtainville family built a chapel here before 1600; Guillaume Croix, a sailor from Hennequeville, married Marie de Surtainville and dedicated it to Our Lady of Pity. In 1761 Robert Croix's heirs kept the plot indivisible among all descendants of Guillaume, each bound to maintain and rebuild it, terms confirmed in 1784 and 1827. The chapel appears on Boissaye du Bocage's 1677 map.

The chapel's name comes from its dedication to Our Lady of Pity, chosen by Guillaume Croix to thank the Virgin for his marriage to Marie de Surtainville. Until 2018 a mass was held annually on the Friday before Palm Sunday; none has been celebrated since. The former children's festival 'La fête de la petite chapelle' included school parades, egg-and-sack races, a domino contest for the 'Domino d'or', and, in 1985, a balloon release.

The chapel is easy to reach on foot from the center of Trouville-sur-Mer, as it sits in the older part of town. Because the building is small and not immediately visible from the main road, having the address ready before you set out will help.

In 1852, a neighbor named Alexandre Lucy tried to have the chapel torn down to improve his view, but descendants of Guillaume Croix took him to court and stopped the demolition. The fact that a private family successfully defended the building through legal action over two centuries after its founding says a lot about how deeply it was considered theirs.
