Our association's mission is to preserve the built heritage of Morbihan during World War II. We inventory, identify, and map the structures built during this conflict and try to understand their use.
 Today, this book allows us to highlight this forgotten heritage, by studying its evolution according to the events of the war and by adding the anecdotes collected throughout our work.
 This allows us to open a page today on the memories that our ancestors wanted to forget, so that future generations do not perpetuate the errors of the past.
