Entrée Abri Sadi Carnot

The Sadi Carnot entrance leads into an underground tunnel system that runs approximately 300 meters from Rue Sadi Carnot to the Tourville military gate. The network connects several chambers that once sheltered the population during wartime and now displays historical photographs and personal testimonies from that period.

The facility was constructed by German forces in 1943 as a defensive shelter and formed part of the coastal fortifications. It became known for the disaster of September 9, 1944, when an explosion claimed the lives of more than 371 civilians.

The site bears the name of the nearby street and now functions as a memorial where artistic works honor those who lost their lives in this place. The inscriptions and portraits create a space where visitors can directly engage with the human dimension of these events.

Access to the shelter is by guided tour only, which allows visitors to safely navigate the underground chambers while receiving comprehensive information. Visitors should wear sturdy shoes and prepare for cool, damp conditions typical of underground spaces.

After the war, the facility was repurposed in the 1960s and briefly served as a nuclear fallout shelter during the Cold War. This transformation shows how military structures adapted to serve different purposes before eventually becoming a space dedicated to remembrance.
