During that operation, Allied troops landed on the beaches of Normandy and broke through the Atlantic Wall, the German defense line that Germany had erected during World War II to protect the coasts of her conquered empire.
The most impressive relics of the Atlantic Wall
To discourage an Allied attack, the German army built a defence line along Europe's beaches from 1942: the Atlantic Wall. Defending Europe's coasts was a daunting task. From Norway, through Denmark, Germany, the Netherlands, Belgium and France, the coastline measured almost five thousand kilometres. The German army therefore concentrated on the most likely places for an Allied invasion: Normandy and Calais.
