Stp Rhl 091 WN 054b is a World War II German coastal defense bunker located near the town of La Ciotat in southern France. This fortification was part of the Atlantic Wall defensive system constructed by Nazi Germany along the French Mediterranean coast. The bunker served as a resistance nest (Widerstandsnest) within the larger Stp Rhl 091 strongpoint, designed to protect the coastline from Allied invasion.
Today, the structure stands as a historical reminder of the extensive military infrastructure built during the war in this strategic coastal region.
