History+
The first documented mention of Grabenstätt dates back to June 8, 959, in a document by King Otto the Great. Originally under Salzburg administration, the area reverted to Bavaria around 1275, but retained its status as a Salzburg demesne, while judicial and sovereign jurisdiction lay with Bavaria. Grabenstätt Castle later became the center of a Hofmark, which in the 18th century belonged to the Counts of Rheinstein and Tattenbach. With the dissolution of the Hofmark in 1803, a history began. A major fire in 1834 largely destroyed the castle.
