The monument of the frigate Laplace
Bay of Fresnaye - Beach of La Mare
On September 16, 1950, the meteorological frigate "Laplace" exploded on a mine in the Bay of Fresnaye, killing 51 sailors. A memorial to the victims was erected next to the Plage de la Mare in 1952. The monument is 8-metre high and represents a ship’s prow from which rises a pyramid, symbolizing the lives shortened by the disaster.
The wreckage of Laplace is one of the most beautiful diving spots in Saint-Cast.
