BP 73 - Stp Flakstellung Küste & Fernstsuchanlage is a World War II German coastal flak and long-range search radar installation located in Denmark. This bunker complex was part of the Atlantic Wall defensive system constructed by Nazi Germany along the Danish coastline. The site features reinforced concrete structures typical of German military engineering from the period, designed to house anti-aircraft artillery and radar equipment for coastal defense.
During the war, such installations formed an integrated network of observation and firepower along occupied European coastlines.
