According to newest findings, the oldest section of the castle wall of Aggstein dates back to the time around 1200.
Indirectly, the castle is first documented with Perchtold von Achstein in the year of 1256.
The Kuenringer family - a powerful political clan in the 12th and 13th century - is often linked to Aggstein until the last heir died in the 14th century.
In 1429, Jörg Scheck vom Wald receives Castle Aggstein as a fiefdom from Count Albrecht V. (later Emperor Albrecht II.) and rebuilt it.
In 1606, Anna von Polheim-Parz became the first private owner of the castle and conducted renovations. After that, Castle Aggstein falls to ruins until the legendary castle was rediscovered in the 19th century and remodeled to become an excursion destination.
In 2003/2004, extensive revitalization work was conducted and the facility became a TOP DESTINATION.
