Chapelle Saint-Gildas de Bieuzy

Chapelle Saint-Gildas de Bieuzy is a chapel built partly into the rock, positioned beneath a granite formation along the Blavet River with two sections arranged in line. Both areas are built from granite and quartz materials, creating an unusual structure that fits naturally into the surrounding stone.

Welsh missionary Saint Gildas and his student Saint Bieuzy founded a retreat in a cave by the Blavet around 538, which eventually led to the construction of this chapel. The building evolved over centuries and was eventually recognized as a historic monument.

Inside, two stone altars honor Saints Gildas and Bieuzy, accompanied by painted plaster statues from the 1800s that show these religious figures. The chapel remains a place where locals and visitors remember these spiritual leaders through the art displayed here.

A hiking trail connects Saint-Nicolas-des-Eaux to this chapel, with parking available around 200 meters away. Visitors should wear good walking shoes since the path goes over rough terrain.

A stone with a deep, resonant tone sits on a granite base inside and produces metallic sounds when struck. This sounding stone was officially protected as a historic monument and draws the attention of visitors exploring the chapel's acoustics.
