Neulengbach Castle was a hilltop castle on a free-standing, around 80 m high mountain cone above the Lower Austrian town of Neulengbach, which was converted into a palace in the 16th and 17th centuries. The palace complex is a three-storey polygonal building with a double defense ring and eight round towers, a porch with a magnificent Renaissance portal and a courtyard with Tuscan double columns and a stone fountain basin.
Neulengbach Castle was founded together with the market by the Freie von Lengenbach around 1189. The castle became the center of the local rule of the Lengenbach family. After the Lengenbachers died out in 1236, it came into the possession of the Babenbergs. In the late Middle Ages, Neulengbach Castle was the seat of princely caretakers and was often mortgaged. In 1565 Rudolf Khuen von Belasy received the rule of Neulengbach. In the 3rd third of the 16th century and in the 1st half of the 17th century, the barons of Khuen expanded the castle into an unadorned late Renaissance castle.
In January 1912 a fire raged in the palace. The entire interior was destroyed. In 1920 the municipality of Vienna acquired the castle and used it as a children's home. In 1952 the Neulengbach Castle Association followed as the owner and in 1962 Martin Wakonig, a businessman from Graz.
