A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes.
The Atlantic Wall was an extensive system of coastal defences and fortifications built by Nazi Germany between 1942 and 1944 along the coast of continental Europe and Scandinavia as a defence against an anticipated Allied invasion of Nazi-occupied Europe from the United Kingdom, during World War II.

The Kriegsmarine maintained a separate coastal defence network, organised into a number of sea defence zones.

The fortifications of Metz, a city in northeastern France, are extensive, due to the city's strategic position near the border of France and Germany.

The German Army decided to build a fortress line from Mulhouse to Luxembourg to protect their new territories. The centerpiece of this line was the Moselstellung between Metz and Thionville, in Lorraine.
