Chapelle Saint-Guirec de Ploumanac'h, Coastal chapel in Ploumanac'h, France.

Chapelle Saint-Guirec de Ploumanac'h is a granite chapel with a main body and a lower side wing, both under steep slate roofs. A small square bell tower with open arches and a single bell sits on the front gable. Inside, white walls and a blue-painted wooden ceiling with exposed beams frame a model three-masted ship hanging near a rounded arch.

The chapel's core dates to the 14th century, when it was linked to the Breton saint Guirec, a companion of Bishop Tugdual. A Gothic nun's-head window and a Gothic interior niche holding a Madonna and Child survive from that medieval building. It was largely rebuilt in the 17th century, then extended in 1938 with a south transept by architect James Bouillé and in 1948 with a north transept, giving it a Latin-cross plan. The statue of Saint Guirec was moved here from the offshore oratory in 1904.

The chapel houses a painted wooden statue of Saint-Guirec and preserves maritime objects that show how deeply the sea has shaped the beliefs and daily life of local communities. These items tell stories of those who worked and depended on the water.

The site is most accessible at low tide, when you can move easily between the granite rocks and reach the chapel with less difficulty. Wear sturdy shoes since the paths over stones and sand are uneven and can be slippery when wet.

The wooden statue of Saint Guirec kept inside the chapel stood until 1904 in the small oratory on a rock offshore, reachable on foot at low tide. It was moved into the chapel that year, while the Calvary in the walled churchyard has been a listed monument since 1930.
