Federal Fortress Ulm-Courtine 6

The Federal Fortress Ulm, which includes Courtine 6, was one of five fortresses financed by the German Confederation, built after the Napoleonic Wars to ensure the security of the German states. Constructed between 1842 and 1859 under the direction of the Prussian fortress construction director Moritz Karl Ernst von Prittwitz und Gaffron, it represented the largest fortification of its time with a polygonal main rampart of approximately 9 kilometers. Courtine 6 originally connected bastions 5 and 7 and could accommodate up to 335 soldiers. Its layout resembled that of Courtine 2, with the rampart behind the caponier extended into a cavalier structure. During World War II, the caponier was damaged by a bomb hit, the traces of which are still visible in the earth covering today. Unlike many other fortresses that had to be razed after World War I, the Ulm Federal Fortress was preserved, although some parts were lost due to war damage and decay.
