World War II.
During the Battle of France, many allied troops were evacuating via the port of Saint-Nazaire. The Pointe Saint-Gildas overlooks the sea where, on 17 June 1940, the RMS Lancastria was sunk with huge loss of lives. A monument and information panel near the main car park commemorates this tragic event. 
Soon after, the Germans set up a major submarine base in Saint-Nazaire at the same time as the defences intended to ensure its protection. This defence was assigned to the MAA 280 (), responsible for prohibiting entry the port of Saint-Nazaire and the mouth of the Loire.
The MAA 280 had 5 batteries, one of which, the fifth, was located on Pointe Saint-Gildas. This battery had two establishments, one on the Saint-Gildas point armed with four 75mm guns and a heavy battery armed with two 240mm guns located above the Raize beach.
These two guns were old pieces of railed artillery used in the First World War. The installation was made at a fixed position with a cannon at the top of the and another halfway down to the sea. The entrance to the known shelters was located at the level of second cannon. Referred to as the “underground hospital”, these shelters were in fact a network of underground bunkers, comprising an infirmary, a radio control post, and a logistics command centre.
Most of the above-ground features are still very visible and some are open for public access. The subterranean shelters, located under what is now the Eléovic campsite mobile home area, are not publicly accessible. The rest of the barracks, as well as the commander's accommodation, were on the site of the campsite.
Following the Normandy landings and Operation Cobra, the area remained under German occupation within the Saint-Nazaire pocket and was not liberated until its surrender on 11 May 1945.
Environment.
Much of the coastal area of Pointe Saint-Gildas was declared a Regional Nature Reserve in 2014. The reserve has been the subject of a major rehabilitation program, in order to reduce the gradual destruction of the biotope by tourist activity. Numerous marked paths have been defined and the moor has been reseeded and stabilized.
