The Grand Site de la Dune du Pilat has been collaborating for more than 10 years with the GRAMASA<\/strong> (Archaeological research group on the Atlantic Wall, Arcachon sector) in order to promote the historical, archaeological and biological research work carried out on the works of the Atlantic Wall.<\/strong><\/p>\n\n\n\n

A significant part of these fortifications was built on the Grande Dune du Pilat (La Grave, les Anguillons) whose Gaillouneys battery, located south of the Dune<\/strong>The latter is one of the most important bunker complexes in the territory and constitutes the Europe's most remarkable and spectacular diving site<\/strong>, since it now forms reefs supporting flamboyant biodiversity.<\/p>\n\n\n\n

Created in 2002, the Gramasa association brings together archaeologists, divers, enthusiasts and volunteers around a common objective: to understand and raise awareness of the remains of the Atlantic Wall submerged off the coast. Sunken blockhouses, bunkers displaced by the movements of sand and swell, visible or invisible traces... These witnesses of the Second World War today form a unique chapter in maritime history and constitute, paradoxically, true refuges of biodiversity<\/strong>.<\/p>\n\n\n\n

Team training and joint actions<\/h2>\n\n\n\n

Gramasa members also ensure the training of mediators of the Grand Site<\/strong> , providing them with the latest archaeological, ecological and historical knowledge about the blockhouses and the coastline. Thanks to this collaboration, visitors and locals will be able to discover the fascinating history and unsuspected wealth of these sites. <\/p>\n\n\n\n

This partnership will be enhanced by new activities (thematic visits, audiovisual promotion of research, films, exhibitions, etc.)<\/strong>. Follow our news!<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
