History+
The Ingolstadt State Fortress underwent several expansion phases, starting with medieval fortifications. After its destruction by Napoleonic troops in 1801, King Ludwig I decided from 1828 to rebuild it as the royal Bavarian main state fortress. Against the resistance of the fortress construction commission and commander-in-chief Wrede, he enforced Ingolstadt as the location.
