You enter a massive, frightening, echoing corridor which sets the scene with lights that dim randomly and the sounds of war in the background. You’re walking into the dome, which is 72 metres in diameter and 5.5 metres thick, created from 55,000 tons of reinforced concrete. Somehow it’s better not to think about it.
Small exhibitions are housed in the vaults. One particularly chilling one deals with the Train to Loos, which departed on September 1st, 1944 from Loos, near Lille. It carried 871 resistance fighters aged between 16 and 71 years old to Sachsenhausen and Buchenwald. By May 1945 only 275 of them were left alive.
