WWII Bunker (Kahl-Burg)
About WWII Bunker (Kahl-Burg)
Kahl-Burg is a remarkably preserved German command bunker from World War II, built in 1942 as part of the Atlantic Wall fortifications following the Allied raid on Dieppe. Carved 20 meters deep into the chalk cliffs of Le Tréport, this underground fortress spans 270 meters of galleries across 4 levels with 32 rooms, including observation posts, combat positions, and a command center with an original 75mm artillery piece still in place. The bunker offers a unique glimpse into the German defensive strategy along the Channel coast, with passionate volunteer guides from the 'Le Mur de la Manche' association bringing its history to life. Access is by guided tour only on specific commemorative dates (May 8, November 11, and European Heritage Days in September), or by appointment throughout the year. Visitors should prepare for 225 steps and a constant temperature of 11°C inside - warm clothing and sturdy shoes are essential. Entry is free, though donations to support the volunteer-run site are appreciated.
Interesting Facts
The name 'Kahl-Burg' means 'Bald Castle' in German, a fitting description for this fortress carved into the bare limestone cliffs rather than built above ground. The bunker was constructed by approximately 200 workers including local French conscripts and Ukrainian prisoners - many of them women - who endured grueling 10-14 hour shifts. Tragically, about 20 workers died during construction and were buried in the nearby cemetery of Eu.
The bunker houses an original Belgian FK235b artillery piece from 1907, which the German forces had captured and repurposed for coastal defense. This antique weapon, still positioned in its firing chamber, represents the resourcefulness of the German military in adapting older equipment for the Atlantic Wall defenses. Visitors can see this authentic piece of military history exactly where it was installed over 80 years ago.
After the German evacuation during the Normandy landings in 1944, the bunker was left unfinished and abandoned. For nearly 60 years it was pillaged, vandalized, and used as an illegal dump site, with locals treating it as little more than a forgotten cave. In 2001, passionate volunteers from the 'Le Mur de la Manche' association began the painstaking work of clearing debris and restoring the galleries, eventually transforming this neglected relic into the remarkable museum it is today.
