The Atlantic Wall Open Air Museum

The Atlantic Wall (German: Atlantikwall) was an extensive system of coastal defence 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 museum is a military museum near Ostend in Belgium which preserves fortifications of the Atlantic Wall dating to the First and Second World Wars. The section of fortifications owned by the museum - over 60 bunkers and two miles of trenches - is among the best preserved sections of the defensive line in Europe. The fortifications survive because they were built on land belonging to Prince Charles, Count of Flanders who decided that they should not be destroyed after the war, but be kept as a national monument.
During the German occupation of Belgium in World War I, the Aachen Battery was built to defend nearby Ostend on the land which forms part of the museum. Though it is not as well preserved as the later fortifications, it is one of the rare coastal defence fortifications that survive from this period.

The majority of the preserved bunkers and trenches at the site date to the construction of the Atlantic Wall during the second German occupation during World War II. Numerous bunkers, gun emplacements and trenches were built on the site, including the well preserved Saltzwedel neu Battery. Several of the fortifications have been renovated to their wartime condition and the museums also displays uniforms and equipment used by the garrison.
