From our Les Saules campsite in Fouesnant, less than 2 km from the pier, Fort Cigogne is a memorable excursion to the heart of the Glénan Islands. This 18th-century fortress, freshly restored and open to the public since September 2024, invites you to discover an exceptional maritime heritage in a natural paradise.
What is Fort Cigogne?
Fort Cigogne is a military fort built in 1756 on Île Cigogne, in the center of the Glénan archipelago. Classified as a historic monument since 2013, it has benefited from an exceptional 5.3 million euro renovation project between 2018 and 2024, selected in particular as part of the Stéphane Bern Mission and the Loto du Patrimoine.
Why was this fort built?
In the 18th century, pirates and privateers from England, Holland, Jersey and Guernsey used the archipelago as a refuge to plunder merchant ships. Fort Cigogne was built to protect the shipping lanes and dissuade these plunderers from frequenting these waters.
Remarkable architecture
- 7-metre-high granite ramparts
- Two defensive bastions
- Military tower from 1911 used as a bitter to calibrate boat speed
- Exceptional panoramic view of the archipelago from the ramparts
- Fully restored historic casemates
An eventful history
Paradoxically nicknamed the “useless fort”, it never really served its military purpose. Privateers soon discovered that an anchorage to the east of Penfret, out of cannon range, allowed them to bypass the fortress. The fort was even the scene of some strange agreements: French garrisons sometimes negotiated truces with the enemy to ensure their supplies!
After its military decommissioning in 1891, the fort has had several lives: refuge for fishermen from Lesconil and Mousterlin, home to Breton families, German occupation during the Second World War, and since 1957, base of the famous Centre Nautique des Glénan, an international benchmark for sailing.
Can I visit Fort Cigogne?
Yes! Since September 2024, Fort Cigogne has been open to the public. An obligation linked to its classification as a historic monument, but also a great opportunity to discover this unique heritage.

- Free access to authorized parts of the fort
- Visit possible during your stopover on Île Cigogne

The Glénan Archipelago: a unique natural setting
The archipelago comprises 8 main islands spread over 144 hectares of land, located around 15-20 km offshore (45 min to 1h crossing time) from Fouesnant and Concarneau. To find out more about this archipelago, read our article on Les Glénan.
Why is the water so turquoise?
The exceptional color of the waters comes from maerl, a white calcareous algae that covers the seabed and reflects the light. You’ll really feel like you’re in the Breton Caribbean!

- Nature reserve home to several endemic species
- Narcisse des Glénan, a unique flower that blooms in April (150,000 plants)
