Burg Liebenburg

Burg Liebenburg is a medieval castle located in the municipality of Liebenburg in present-day Germany. It was originally built by the bishops of Hildesheim to protect their eastern territorial border against the expanding influence of the Dukes of Brunswick.

Construction of the castle began in 1292 under Bishop Siegfried II of Hildesheim and was completed around 1302. Its initial purpose was that of a fortress securing the prince-bishopric’s frontier, playing a key role in regional defense. By the mid-14th century, from 1366 onward, the castle also served as a pawn possession to the nearby city of Braunschweig (Brunswick), acting as a base for controlling trade routes leading to the important mining town of Goslar.

Throughout the 14th and 15th centuries, various noble families including the von Schwicheldt and von Cramm clans held the castle through pawn agreements. In the early 16th century, control shifted when Duke Heinrich the Younger of Brunswick-Wolfenbüttel took possession in 1523. Notably, he used Burg Liebenburg as a place of concealment in 1541 and 1542 for his mistress Eva von Trott and their children.

The castle endured military pressures during the religious and political conflicts of the 16th century. Troops from the Schmalkaldic League occupied it in 1542, but it was later recaptured by the duke in 1547. A brief occupation by Count Vollrad von Mansfeld occurred in 1552. During the Thirty Years’ War, in 1625, the castle served as headquarters for the imperial general Albrecht von Wallenstein. The castle sustained heavy damage in 1633 when Swedish forces attacked. According to historical reports, the defending garrison escaped overnight using a secret underground passage, the existence of which was confirmed much later in 2005 through archaeological investigation.

Following the war, Burg Liebenburg returned to the control of the Hildesheim prince-bishopric in 1643 through a formal treaty. In the mid-18th century, Prince-Bishop Clemens August ordered the demolition of what remained of the damaged medieval fortress. He initiated the construction of a Baroque-style pleasure and hunting lodge on the site, including a chapel dedicated to the Annunciation. However, work on this new building was left incomplete due to the outbreak of the Seven Years’ War in 1756. The west wing of the lodge was finished and eventually served as the local government office and court until 1959. Since 1974, this building has been privately owned and is used as a residence and studio by the artist Gerd Winner.

Restoration efforts began in the 1990s to preserve the surviving elements of the original castle, focusing on the repair of towers and defensive walls.
