Fort Cigogne

Fort Cigogne is a stone fortress on Cigogne Island with granite ramparts approximately 7 meters high and two distinct bastions on its western and southern sides. The structure displays typical coastal defense features with thick walls and strategic positioning for protection.

Construction began in 1756 following a request to protect against English and Dutch privateers operating in the archipelago. It became part of a coastal defense network during 18th-century conflicts in Brittany.

The fort has served many purposes over the decades, and today it hosts sailing school activities and training programs. Visitors can observe how the space functions as a living center for maritime education rather than a purely historical monument.

The site has undergone extensive renovation since 2019 to modernize its facilities while preserving historical character through local authority and conservation partnerships. Access to certain areas may be limited during ongoing restoration work.

From 1891 to 1930, the fort served as a center for marine research where scientists studied sea biology and collected weather data. This work contributed to improved navigation aids for ships in the region.
