In winter, the fortress remains closed
The only completely preserved fortress of old Austria to protect the southern border of Tyrol. The fortress was built around 1840, the barracks with their bunkers embedded in the mountain are located opposite. The early medieval defensive wall, the “Nikalas Wall” went out from here and up the mountain. You can still view some of its remains.
