Austro-Hungarian fortress closures in Tyrol and Carinthia
In the first half of the 19th century, the territory of Tyrol and Carinthia lay deep in the interior of the Austrian Empire, so there was no need to pay special attention to its defense. The only significant fortifications of this period were therefore the Franzensfeste fortress, protecting the entrance to the Brenner Pass, and several small road closures, such as Nauders at the Swiss border.
