Federal Fortress Ulm-Courtine 4

The Bundesfestung Ulm, to which Courtine 4 belongs, was one of five federal fortresses financed and built by the German Confederation in the 19th century. It was constructed between 1842 and 1859 under the direction of the Prussian fortress construction director Moritz Karl Ernst von Prittwitz und Gaffron. Courtine 4 was a connecting structure between bastions 3 and 5. In 1865, a passage was created in the right flank battery to relieve the other gates. Although demolition began in 1919, work had to be halted under government pressure. The material already recovered was used in the renovation of the Catholic garrison church and the erection of a war memorial.
