Kropfsberg Castle was
constructed in the early 12th century by the orders of Archbishop
Konrad I of Salzburg.
Originally it started as a central tower surrounded by the wall. The
archbishops used the citadel as the seat of the Salzburg court and
administration. Kropfsberg was first mentioned for the first time in
1286 in the official documents. Archbishop Eberhard II of Regensburg
extended the defenses of the citadel further. Much of its current
appearance date back to these renovations.
In 1412 Kropfsberg Castle
became the center of important negations between Austrian provinces
of Tyrol and Bavaria. In 1416 the Emperor of the Holy Roman Empire
Frederick IV and his brother Duke Ernst of Austria came to
reconciliation over territorial disputes. In 1592 the court seat was
moved from Kropfsberg Castle to Zell am Ziller. The fort was largely
abandoned and fell in disrepair.
Today Kropfsberg Castle is
open to the public. Its impressive walls measure 900 meters in total
length, 8 meters in height with a total thickness of 3 meters. It is
one of the best and largest citadel in the Austrian province of
Tyrol. Defenses of Kropfsberg Castle include double protective wall.
The inner area include 26,000 square meters with a total garrison of
80 to 100 people.
