The church tower was historically used by local sailors and customs officers as a surveillance point for monitoring coastal activity.
The masonry incorporates gray granite, which is characteristic of the architectural style found in the historic salt-producing region of the Guérande.
A series of external buttresses and pinnacles define the Flamboyant Gothic exterior, reflecting the wealth derived from the local salt trade during the medieval period.
The site has been a place of worship since the 10th century, though the extant building dates primarily to the late Middle Ages.
The church contains a collection of 17th-century wood carvings that depict regional religious traditions.
Saint-Guénolé Church is a historic landmark in Batz-sur-Mer, noted for its prominent 57-meter-high bell tower that serves as a coastal navigation point. The current structure, built between the 15th and 16th centuries, replaced a Romanesque predecessor and stands on the site of earlier religious foundations. It is classified as a Monument Historique, featuring a blend of Flamboyant Gothic architecture with distinctive local granite construction. The interior houses significant artifacts, including 17th and 18th-century statuary and carved woodwork. The tower offers a vantage point overlooking the Guérande peninsula and the neighboring salt marshes. It remains an active parish church dedicated to Saint Guénolé, a Breton saint who founded the Abbey of Landévennec. Visitors can observe the influence of maritime history through various votive offerings preserved within the nave.
