Burg Neuhaus, Water castle in Wolfsburg, Germany

Burg Neuhaus is a medieval water castle in the Wolfsburg district of Neuhaus, built on a Keuper sandstone rock above the Aller floodplain. Its square plan encloses a courtyard of about 33 by 30 metres, with a 20-metre bergfried beside the gate and a round corner tower in the south-west. The moats, fed by the Hehlinger Bach, are now dry except for the castle pond.

Burg Neuhaus was built in 1372 in just two years by Duke Magnus the Younger of Brunswick as a counter-castle against the Wolfsburg and the Old House in Vorsfelde, both held by the von Bartensleben family. From 1423 it was the seat of the Rothehofer line of that family. In 1552 troops of Count Vollrad von Mansfeld shelled it heavily; the castle chapel was never rebuilt, and the castle became an ducal administrative office and agricultural domain.

The castle's name, Neuhaus ("new house"), comes from its completion in 1372 after just two years of building, when Duke Magnus the Younger of Brunswick raised it against the von Bartensleben family. From 1585 to 1890 a brewery and a distillery operated in the castle's farm buildings, part of the ducal domain. After 1946 the state of Brunswick ran a youth hostel in the castle.

The castle stands on a Keuper sandstone rock above the Aller lowland; the Hehlinger Bach once fed its moat, and only the Burgteich pond remains. The inner courtyard buildings date from the 20th century, while the Palas with the Rittersaal is original. The site is owned by the city of Wolfsburg.

The castle's cellar once held a well, filled in only about 50 years ago, and the bergfried's original pointed-arch entrance is now walled up. The round corner tower in the southwest and the stone bridge replacing the drawbridge show how the defensive layout was altered over centuries.
