Abbey · Sankt Paul im Lavanttal
Fortress
Rabenstein Castle began as a mere watchtower built on a tall hill. Rabenstein became a castle when Engelbert I Sponheim, Margrave of Istria founded St. Paul's Abbey in 1091 in order to protect the abbey and town around it.
The castle was occupied by the Rabensteins (whose name henceforth stuck to the structure) until 1200, the Archbishop of Salzburg until 1300,
