Zantyr (Polish: Santyr, Zantir, German: Zantirburg, Burg Zanthir.) is a lost Teutonic Order castle with established commandry and town with cathedral, seat of the bishopric. In the early 13th century it was located at present day Pomeranian Voivodeship, in Sztum County, in the municipality of Sztum, south of the village Uśnice or in the region Biała Góra at the confluence of the rivers Nogat and Vistula.
Localisation
Here, at the southern end of the Vistula delta region (Żuław Wiślanych), resides the Nogat River Protected Landscape Area. During its brief history Zantyr was contested between Swietopelk II, Duke of Pomerania, State of the Teutonic Order and Bishopric of Pomesania. At the end around year 1280 the castle and town were reestablished at a new location and became known as Malbork Castle.
