Untere Stadtkehle (Werk XXVI)

Untere Stadtkehle (Werk XXVI) stands in Ulm as one section of the nineteenth-century Bundesfestung Ulm, an extensive fortress complex. This work formed part of the city’s defensive network. Constructed in the mid-nineteenth century, it connected with neighbouring works along the southern defensive line. That position helped create a continuous barrier for Ulm and its surroundings. Its numbered works each served a specific purpose in the overall defence.

The wider complex ranked among Europe’s largest fortresses of its time, using bastions and curtain walls to build a formidable defence. Roman numeral XXVI marks this section’s place within that arrangement. Careful planning joined separate structures, reflecting the defensive priorities and engineering practice that shaped the period’s military construction. The fortress also represented power and control through its scale and design. These elements made the southern line a connected defensive system. The designation leaves a precise clue: XXVI identifies one link within Ulm’s larger defensive structure.
