Groswin

Groswin was the name-giving seat of one of the castellanies of the Duchy of Pomerania in the High Middle Ages.

The castellany is thought to have comprised the area between the rivers Peene and Zarow, and the villages Rehberg, Japenzin, Iven, Crien, Wegezin, Thurow, Blesewitz and Görke.

[3] The exact location of the Groswin burgh, which was destroyed in the late 12th century,[4][5] is uncertain, it may have been near Stolpe-Neuhof, Grüttow, Görke or Müggenburg.

[8][9][10] Groswin took over the position of nearby Altes Lager Menzlin as a trade center after its decline in the 9th century.

[13] The lands of Groswin became a castellany of the Duchy of Pomerania during the westward expansion of Wartislaw I in the 1120s, and became part of the Bishopric of Cammin in 1140.
