Liechtenstein

A ministerial family of free origin with a stone castle on the edge of the Wienerwald south of Vienna (built about 1130) and its own allodial lordship of Petronell and Rohrau near the Hungarian frontier, which become the family's main seats.

A choir tower was added to the castle chapel by about 1220.
