Liebenburg

The Liebenburg was a medieval spur castle in Liebenburg in Lower Saxony, which was built between 1292 and 1302 and, with its seven towers, was considered one of the strongest castles in the Harz foothills. Today, only individual parts of the outer bailey such as defensive towers and sections of the ring wall remain, which were extensively renovated from the 1990s onwards. The castle complex, which had been severely damaged over the centuries by the effects of war, was demolished in 1750 by the prince-bishop of the Hildesheim Bishopric, Clemens August. In its place, he built an unfinished baroque pleasure and hunting lodge with the castle church of the Annunciation, which is now privately owned.
The castle complex was located in an elevated position on a mountain spur on the eastern slope of a spur of the Salzgitter mountain range. Today, only a few parts of the complex are still present. These include three of the seven towers, including the mighty Hausmannsturm, a defensive tower of the ring wall and the base of a defensive tower. In addition, some sections of the ring wall have been restored during a renovation.
