Rio Pusteria Fortress

At the entrance to the Val Pusteria valley, an ancient Habsburg customs and fortification site can be visited

Near Rio Pusteria village, an impressive fortress - "Mühlbacher Klause" in German, "Chiusa di Rio Pusteria" in Italian - whose history dates back to the 13th century can be admired still today. At that time the border between the counties of Gorizia and Tyrol ran here, which made the construction of a border fortress necessary. This "Old Fortress", in which the customs clearance of the goods transports took place, was located approx. 600 m west of the today's site. The present complex, the "New Fortress", was built in the 15th century.

Some parts of the building were destroyed after a flood in the 18th century, the rest was preserved, but fell into disrepair when the actual purpose as a fortress and customs station ceased to apply. The complex in its present form consists of a round tower, which shows the defensive character, a ring wall more than one metre thick, a guard's house and the dwelling with storerooms and armouries. Those who wanted to pass through had to pass the gate tower: The walls inside the passage were provided with loopholes.

The Rio Pusteria Fortress Association restored the building in cooperation with the Province of South Tyrol, the Department for the Preservation of Monuments, the Cassa di Risparmio Foundation and the municipality. Today it is open to the public again. And how to reach the Rio Pusteria Fortress? It is located directly on the Val Pusteria Road, parking is available. Also the "Pusterbike" Cycle Path - which leads from San Candido to Fortezza - passes here.
