Port of Lanildut
Aber Ildut fire

The port of Lanildut saw intense traffic when the granite quarries of Aber-Ildut supplied Europe with quality stone, and local barges carried out a profitable coastal trade from the ports of the Atantic to those of the English Channel and North Sea. Granite blocks, as well as wheat, wine, sails and linen were commonly transported.
In times of war with England, all these goods were easy pickings for an enemy with numerous, intrepid vessels. From then on, defending the port of Lanildut became crucial.
It was under Louis XV, during the War of the Austrian Succession, that a battery was installed at the entrance to the port.

From these once famous granite quarries, the base of the Concorde obelisk in Paris was extracted in 1836.

Located on the north bank of the Aber-Ildut, Manoir de Bel Air was built by Francois de Kerengar, on land he received on his marriage to Louise de Kerbescat in 1585. Construction lasted around 14 years, until 1599.
Built on a square plan around an enclosed courtyard, its architecture is typical of the fortified buildings of the Lower Middle Ages in Brittany. Its defensive layout is explained by its proximity to the sea, a source of danger.
