Enthusiasts in France are restoring some of the most impressive remnants of World War II.
Built by the occupying Germans as a defence against invasion the so called Atlantic Wall stretched all the way from the Spanish border to Scandinavia.
For decades it has been left to disintegrate but now a new generation has started work on renovating the wall and sharing its history.
