OB 5cm KwK

OB 5cm Kw K is a World War II German military bunker located near Wimereux, in the Pas-de-Calais department of northern France. This coastal defense position was part of the Atlantic Wall fortifications built by Nazi Germany to defend against Allied invasion. The designation 'OB' indicates an observation bunker, while '5cm Kw K' refers to a 5cm Kw K (Kampfwagenkanone) gun mount, suggesting it housed a light anti-tank or infantry support weapon. Situated along the English Channel coastline, this fortification formed part of the extensive defensive network protecting the Pas-de-Calais region, which was strategically important due to its proximity to England.
