The Maginot Line was a line of concrete fortifications, obstacles, and weapon installations built by France in the 1930s to deter invasion by Germany. Think of it as a giant, impenetrable wall meant to keep the bad guys out. However, it proved ineffective because the Germans simply went around it during World War II. It became a symbol of misplaced faith in defensive strategies. The Maginot Line serves as a cautionary tale of relying too much on rigid planning.
