Retranchement, i.e. the fear framed by two masonry cuts and a coast guard healer (ZL 39, 40; ZK 3): inscription by order of 30 October 2000
Origin and history
A typical example of the 17th and 18th century coastal fortifications is the Borbardoué cut-off, located at the Palace on the island of Belle-Île-en-Mer. Built after France took over the island in 1763, it was part of an extensive defensive program launched in 1745 to secure strategic landing points. The work consists of a diamond dread framed by two masonry cuts, as well as a coast guard heal, one of the few still preserved on the island.
The dread and its cuts had the task of controlling access to the beach, while the cure allowed for permanent surveillance, day and night. This defensive system reflects the military concerns of the time, marked by maritime conflicts and the need to protect the Breton coasts. The protected elements, inscribed in the Historical Monuments in 2000, include dread, oppression and healing, now owned by a private company.
The location of the site, although documented (approximate address: 1151 Bordardoué, Le Palais), suffers from poor accuracy according to available sources. This monument illustrates the military architecture of its time, combining masonry and strategy to meet the geopolitical challenges of the 17th and 18th centuries in Brittany. Its conservation status and current accessibility (visit, rental) are not specified in the sources consulted.
