The Atlantic Wall, an extensive system of coastal fortifications, was built between 1942 and 1944 by the German Third Reich, to defend against an anticipated Allied invasion of mainland Europe. Stretching over 5,000km along the western coast of Europe, it runs from the top of Norway down to the top of Spain, and consists of many different types of concrete fortifications, from ammunition bunkers, to gun emplacements, to supply depots and submarine stations. Over the years, we have visited all of the sites along the entire length of the Atlantic Wall, and one of the highest concentrations of fortifications can be found at Hanstholm, on the west coast of Denmark.
On the way southeast out of Berlin, you should take a ride along Mühlenstraße and visit the East Side Gallery.

It features murals by artists from all over the world, painted in 1990, just after East suddenly became West, and the overpowering desire for freedom dissolved what was known as the "Anti-Fascist Protection Rampart" (In German: Antifaschistischer Schutzwall).
