The transaction at the time was 0.25 francs per square meter. It was completed around 1896 by the engineer Lanmoniez and the Lannionnais entrepreneur Pierre Le Tensorer. After her death in 1900, her daughter, Sofia Abakanowicz, who had become Madame Poray, had the villa extended by a wing to the west in return on the rear facade.
During the Second World War, the villa was requisitioned by the German army, and suffered some interior damage.

Citadel of Bréhat and Glass Workshop
Highlight • Castle
Worth seeing is also the glass art studio. One can watch in the production of art objects, which can be bought in the shop also commercially.
A tour around the citadel is worthwhile because of the rock formations, the grove and the view of the sea. A bank off the beaten path is perfect for a break with stunning views of the mainland.

The fort is accessible via a drawbridge, and its walls offer breathtaking views over the cliffs and the endless expanse of the sea. Between the towers, battlements, and cannons, history is palpable—and it's easy to understand why this place has often served as a film set, including "The Vikings" starring Kirk Douglas.

A medieval fortress originally built in the 12th century and reconstructed multiple times throughout its turbulent history. The castle was demolished in 1395 by the Duke of Brittany due to its owner's rebellion, then rebuilt in 1406, and partially dismantled again in 1626 on Richelieu's orders after another conspiracy. The fortress features impressive defensive architecture including a barbican, gatehouse with 6-8 meter thick walls, and two major towers - the Tour de Rougé and Tour d'Acigné - both over 20 meters high.
