A military bunker located near the coast of northern France, in the Pas-de-Calais region. This area was heavily fortified during World War II as part of the Atlantic Wall defenses constructed by Nazi Germany. The Vf HWB designation suggests it is a standard German Regelbau (standardized bunker) type, likely built to house defensive positions or observation posts.
The region around Boulogne-sur-Mer saw significant military activity during both World Wars, with numerous fortifications still visible today.
