History+
The first documented mention of the locality Raben Steinfeld dates back to January 11, 1410, but a German castle already existed here around 1160. The name of the place derives from the noble family von Raben and the stony fields of the surrounding area. After the Thirty Years' War in 1648, the area became part of Mecklenburg. In 1679, ownership went to Helmuth von Plessen and in 1683 to Duke Christian Louis I of Mecklenburg-Schwerin. From 1847, Raben Steinfeld belonged to the private estate of the Grand Dukes of Mecklenburg-Schwerin.
