Île-d'Arz, commune in Morbihan, France
Île-d'Arz is a small island in the Morbihan Gulf covering about 330 hectares with a permanent population of roughly 250 residents. The landscape is crossed by narrow pathways leading to beaches and green spaces, with the sea visible from nearly every point on the island.
The island has been inhabited since ancient times, as shown by the megaliths and dolmens scattered across it. A church was built in the 12th century, and in the 16th century both the tide mill Moulin de Berno and the manor Kernoel were constructed, marking the island's long maritime and agricultural past.
The name comes from the Breton word 'Arz', meaning bear. Today, maritime traditions shape daily life through fishing heritage, the colorful boats in the harbor, and summer festivals where locals and visitors gather to celebrate songs of the sea and community bonds tied to the water.
The island is reached by boat from Vannes in under 20 minutes, with regular ferry services from several companies. Exploring on foot or by bicycle is the best approach, since roads are not open to vehicles and you can discover the island at your own pace.
The Moulin de Berno is a rare functioning tide mill where water movement powers the grinding mechanism instead of wind. Restored by volunteers, visitors can observe how this ancient energy system actually worked and gain insight into the engineering ingenuity of past centuries.
