Located in crater-scarred countryside, 10km northeast of Verdun, this fort was constructed between 1881 and 1884. It was the second fort – Douaumont was the first – to fall in the Battle of Verdun, and became the site of bloodiest battle for two months. Weak with thirst, Major Raynal and his troops surrendered to the enemy on 7 June 1916. You can gain an insight into past horrors by taking a tour of its dank interior and observation points.
