Schuster Line
The Schuster Line (Luxembourgish: Schuster-Linn, German: Schusterlinie) was a system of barriers and barricades erected by the Luxembourg government along its borders with Germany and the 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, including 18 bridge barriers along the German border and five roadblocks on the French border.
