Historic Churches of Carnac

Carnac’s religious heritage features 17th-century architecture, active monastic communities, and historic hilltop landmarks. The town center is dominated by the Église Saint-Cornély, known for its ornate stone porch and painted ceilings. Nearby, the twin Benedictine abbeys of Kergonan continue traditions of Gregorian chant. Coastal and elevated sites, such as the Chapelle Saint-Michel atop a Neolithic tumulus and the 16th-century Chapelle Saint-Colomban, illustrate how spiritual sites have been integrated into the Breton landscape over centuries.
