The Reduit Tilly is the centerpiece of the bridgehead of the Ingolstadt state fortress on the southern bank of the Danube . It was built from 1828 to 1841 under King Ludwig I according to the plans of his court architect Leo von Klenze and the fortress builder Major General and Head of the Engineer Corps Michael von Streiter in the classical style . The semicircular two-storey building, closed off from the bank by the so-called infantry wall, was intended to accommodate guns and troops in its barrel-shaped casemates . It was also intended to offer refuge to the Bavarian royal family and the crown jewels in the event of an invasion . Two flank batteries and the oval fortress structures Turm Triva and Turm Baur adjoin it at the side . It is named after the general of Bavaria in the Thirty Years War , Johann T'Serclaes von Tilly . In connection with the State Horticultural Show in 1992, the Reduit was renovated and integrated into the Klenzepark . Today it houses the permanent exhibition of the Bavarian Army Museum on the First World War .
