Le château en bref

The secondary battery 8/AR 275, known as ‘Berta’, at the locality of Clos-Bertin, is a German coastal defence work of the Atlantic Wall, built between spring 1942 and spring 1944 and attributed by historical studies to the Organisation Todt. It comprises four H 669-type casemates, designed for 105 mm guns (K 18/40), and two passive reinforced-concrete bunkers. One of the casemates is located in the neighbouring commune of La Turballe. The battery belonged to the 3rd group of the 275th Artillery Regiment, the northernmost on the Guérande peninsula, together with the Carpadoux (7/AR 275) and Garenne (9/AR 275) batteries. The four casemates on record survive as remodelled remains, on private land, with no mention of protection as a historic monument.
