The Schuster Line was a line of fortifications erected in Luxembourg shortly before World War II. It was named after the Luxembourger charged with its construction, Joseph Schuster.
The Line consisted mainly of concrete blocks and iron gates at the bridges on the border with Germany. Inland, there were also blockades on some of the roads leading to France and Germany. The Line did not have much influence on the Wehrmacht's progress. The iron gates were simply torn down, and ramps were built over the concrete blockades to drive over them; in other cases, they were blown up.
