A German military bunker located on the northern pier in Hook of Holland, Netherlands. This Type 611 bunker was constructed in 1943 as part of the Atlantic Wall defensive system during World War II. The structure was designed to house a field gun and served as part of the extensive coastal fortifications built by Nazi Germany along the western European coastline.
Today, this bunker is part of the Atlantikwall-Museum, which serves as the Dutch centre for knowledge and education about the Atlantic Wall and its historical significance.
