A Walzkörpersperre is a type of anti-tank obstacle barrier commonly found in the Netherlands, designed to block or slow the advance of armored vehicles. These structures were part of the country's defensive infrastructure, particularly during World War II and the Cold War era. The term 'Walzkörpersperre' refers to a rolling body barrier, typically consisting of large concrete obstacles arranged to impede vehicle movement.
Such barriers were often integrated with other defensive measures like bunkers and trenches to create comprehensive defensive lines.
