A destroyed 2.5cm Flak (anti-aircraft gun) position located in southern France, near the town of Saint-Thomé. The site was part of the German military fortifications during World War II, specifically designed to defend against Allied air attacks. The designation 'Feldm. OB' indicates it was a field command observation post, while 'zerst.' confirms the position was destroyed during or after the war.
This type of Flak position was common along the Rhône Valley, a strategic corridor for both German supply lines and Allied bombing campaigns.
