Fortress Linz-Tower XV (Luitgarde)

The Linz tower fortifications, also called the Maximilian Tower Line, were built in the early 19th century on the initiative of Archduke Maximilian Joseph of Austria-Este. His experiences from 1809, when Napoleon's advance on Vienna could not be stopped, led to the proposal of an imperial fortification system. This envisioned protecting strategic locations with a line of individual towers. Only the fortification of Linz was realized. The idea was to create a ring of fortification towers around the city, mutually covering each other and forming an advanced defensive line to keep enemy artillery at bay. Maximilian preferred simpler, more densely arranged towers, which were also protected by a glacis.
