Fort des Sept-Îles, Historic fort in Perros-Guirec, France.
Fort des Sept-Îles stands on a rocky archipelago off the Pink Granite Coast, surrounded by distinctive geological formations and clear waters of the English Channel in Brittany.
Built in the 18th century to defend the coastline against maritime attacks, this fort demonstrates the strategic importance of the region during European naval conflicts throughout history.
Designated as a historic monument since 2020, the fort represents a remarkable example of French military architecture and the defensive heritage of maritime Brittany.
Accessible only by boat excursions departing from Perros-Guirec or Trégastel, visits last approximately two hours and accommodate visitors with reduced mobility upon advance reservation.
The fort is located within France's oldest ornithological reserve, hosting over 27 breeding bird species including the country's only colony of northern gannets on Rouzic island.
