To be privately owned
Batthyány Castle

The Batthyány Castle is a palace building in Güssing in Burgenland. The Batthyány Castle is not to be confused with the Güssing Castle, which is also owned by the Batthyány family.
The castle is a building from the 1760s with a hook-shaped floor plan, two stories high and with arcades enclosed by glass windows.
King Louis II transferred Güssing Castle as a reward for the victory over a Turkish army at Jaice to the Hungarian noble Franz Batthyány and his nephew Christoph. The family had the castle expanded from the 16th century due to the looming threat from the East.
