Schuster Line

The Schuster Line (Schuster-Linn, Schusterlinie) was a line of barriers and barricades erected by the Luxembourg government along its borders with Germany and France shortly before World War II. The line was named after Joseph Schuster, Luxembourg's chief engineer of bridges and highways, who was responsible for its construction.

The Schuster Line consisted of 41 sets of concrete blocks and iron gates; 18 bridgeblocks on the German border, and five roadblocks on the French border. The roadblocks were set up a mile inland in a zigzag pattern, covered by barbed wire entanglements on either side. Nine radio outposts were erected along the German border, with a central receiving station in the St Espirit barracks in the capital.

The line failed significantly to slow the German advance during the invasion of Luxembourg on 10 May 1940. The iron gates were knocked down and ramps were built over the concrete blockades to drive over them; some were blown up.
