Burg Neulengbach, Medieval castle in Neulengbach, Austria.

Burg Neulengbach is a castle on a free-standing hill cone about 80 m above the town of Neulengbach in Lower Austria. It was rebuilt in the 16th and 17th centuries into a three-storey polygonal palace with a double defensive ring and eight round towers. A forebuilding carries a rich Renaissance portal, and the courtyard has Tuscan double columns and a stone fountain basin.

The Lengenbach family founded the castle and market around 1189, moving their seat from Altlengbach to the hill above Neulengbach. A 1197 charter of Bishop Wolfger of Passau names Otto IV of Lengenbach and his son Hartwig III. After the last Lengenbach died in 1236, the Babenbergs took over; later the Truchsess von Lengenbach enlarged the palas and raised the towers by two storeys. In the 16th and 17th centuries the fortress was rebuilt as a castle.

The name Neulengbach distinguishes the site from Altlengbach, seat of the Lengenbach family before they moved here around 1189. Under Otto V of Lengenbach the castle hosted minnesingers such as Ulrich von Liechtenstein, Neithart von Reuenthal and Gottfried von Totzenbach. The market grew alongside the castle from its founding.

The location sits just a short drive from Vienna and is easily reachable for day visitors. When you visit, be prepared for hilly terrain and wear proper shoes, since the paths lead over uneven ground and stairs.

The castle was rebuilt in the 16th and 17th centuries into a palace, so the medieval walls were largely replaced. What visitors see today is a three-storey polygonal building with a double ring of walls and eight round towers, plus a Renaissance portal and a courtyard with Tuscan double columns and a stone fountain basin.
