The Schwinge Ditch near Klein Zastrow

The Schwinge rises west of Behrenhoff and is approx. 24 km long. It flows into the Peene near Loitz. The valley north of the Os Range was originally wider. Over time it grew up as a fen. Since the lowland is very moist and wet depending on the weather, it is used as grassland.
In a document from Duke Casimir II from 1219, the stream was mentioned as “aqua molendini” (mill water). It was mentioned as “Zwinga” in 1248 in a document from Duke Wartislaw III. von Pommern-Demmin when describing the boundaries of the Hilda monastery with the goods of the knightly families von Behr and von Blixen. In 1248 a watermill near Dersekow and another near Subzow were mentioned, and in 1280 five mills on the Schwinge were reported. The swing arm was dammed up to operate the water mills.
