Wagria Castle occupied a central location in Oldenburg in Holstein (then called Starigard, or "Old Castle"); its ramparts still exist.
Granted Wagria and Segeberg by Duke Henry the Lion in 1143, Count Adolf II of Holstein founded the new German settlement of Lübeck four kilometres from Liubice on a peninsula called Bucu at the confluence of the Wakenitz with the Trave.
In the years which followed Vicelin's mission, the Emperor Lothair II thoroughly encastellated Wagria and Canute Lavard and the Holsteiners invaded it and took Pribislav and Niklot, the Wagrian leaders, away in chains.
