Type 611 Bunker at Hook of Holland

A German-built Type 611 bunker located on the northern pier in Hook of Holland, Netherlands. This coastal defense structure was constructed in 1943 as part of the Atlantic Wall, Hitler's extensive system of fortifications along the European coastline. The bunker was designed to house a field gun and served as a defensive position during World War II. Today, it forms part of the Atlantikwall-Museum, which serves as the Dutch center for knowledge and education about the Atlantic Wall and its historical significance.
