In East Frisia, Lütetsburg Castle is a moated castle that gave its name to the municipality of Lütetsburg. The complex, consisting of a residential building, an outer bailey, and a park, is located east of Norden and has undergone several transformations.
History+
The castle's origins date back to 1212, when an outpost of the Manninga chieftain family existed on this site. Around the mid-14th century, Lütet I. Manninga expanded it into a stone house, thus becoming its namesake. His nephew Lütet II. relocated the family seat to this storm-surge-proof location after the destruction of the old residence in 1374. By 1430, Lütet III. had expanded the stone house into a four-winged castle. In 1514, the castle was destroyed by the Black Guard during the Saxon Feud. Between 1557 and 1576, under Chieftain Unico Manninga, it was rebuilt as a Renaissance castle, supplemented by an outer bailey that still stands today. Through marriage, Lütetsburg passed into the possession of the Knyphausen family in 1588. During the Thirty Years' War, the castle was occupied multiple times, and its structure suffered greatly. From 1677 to 1679, a reconstruction in the Classical Baroque style took place.
