Hollerather Knee - West Wall - Siegfried Line

Dragon's teeth (in German: Höckerhindernisse) are pyramid-shaped concrete obstacles that were built by the Germans during World War II, often as part of the Atlantic Wall and the Western Wall, to stop enemy tanks that had landed via a warship and then a landing barge on the beach, in the dunes. Rows of dragon's teeth were often an additional support for the tank wall of the Atlantic Wall or for the weak points of the panzer walls. They also served as an alternative to tank ditches if the soil was not suitable for digging tank trenches. Due to the early low rows of dragon's teeth, tanks were launched into the upper dragon's teeth, causing severe damage or overturns to the tanks, leaving survivors with little choice but to abandon the tank. Infantry (the men who continued on foot) could easily be eliminated in this way. During the Russian invasion of Ukraine in 2022, dragon's teeth were deployed by the Russians. Unlike the dragon's teeth from World War II, the pyramid-shaped concrete blocks were not anchored in the subsoil by the Russians.
