Altfinstermünz

Altfinstermünz is a castle built on a rocky ridge between steep cliffs, overlooking the deep gorge of the Inn River. The complex spreads across multiple levels with living quarters, watchtowers, and storage areas all constructed on the rock face.

The fortress was established in the 11th century as a crucial customs checkpoint monitoring trade between Austria and Switzerland through this Alpine pass. Over centuries it was enlarged and reinforced to reflect the growing importance of this mountain crossing.

The castle houses the only surviving medieval customs station in Tyrol, where you can see objects and documents from centuries of border operations. The rooms show how people worked here daily to check goods and monitor travelers.

The castle is open from May through September, typically Tuesday to Sunday, with guided tours available in several languages. Visitors should wear good footwear as the access path is steep and rocky with numerous stairs.

A wooden bridge crosses the Inn River from the castle, connecting it to the opposite bank. Ducal workers carved a watchtower directly into the rock face, merging the structure seamlessly with the mountain itself.
