Reduit Tilly and Klenzepark, Ingolstadt

The Ingolstadt State Fortress was a fortress of the Bavarian Army, laid out on the right and left of the Danube River around Ingolstadt.

In the course of the reconstruction of the original medieval fortification as well as the subsequent expansion of the Ingolstadt state fortress, a total of five main phases can be distinguished, which are presented below. It is remarkable that in Ingolstadt, in addition to the almost completely preserved medieval city wall, the works from the later phases have also been preserved, if not completely, then at least to a considerable extent, and thus convey a vivid idea of how the city was shaped by the fortifications at the respective time. After the postwar thesis that the remaining fortification works should be eradicated from the cityscape was dropped, the classicist fortification works in particular were restored and put to new uses.
