Gröningen is a deserted medieval settlement in the north of Hamelin in Lower Saxony. The settlement, which was once located to the west of the Schweineberg near Holtensen, is one of a number of towns around Hamelin that have disappeared in the Middle Ages and modern times.
During the Middle Ages, up to five farms belonged to Gröningen. The settlement still existed around 1350, but fell into disrepair towards the end of the 14th century. In two undated documents it is mentioned as Groninge and Groningen. On a map from 1760, the former location is marked "Die Haus-Stetten". Today, the approximately one square kilometer Gröninger Feld bears witness to the earlier settlement. It was created as a clearing island in the middle of a forest area and used to be the agricultural area of Gröningen. The settlement was centrally located in the Gröninger Feld on the Krummen Beeke stream. This is probably a dip in a pasture near a power line.
The Hamelin Landwehr ran close to the town as an outer protective ring around the town; it was created around the second half of the 14th century. To the north and east of the Gröninger Feld, these systems have survived in places in the forest. Not far from the settlement of Gröningen was the Holtenser Warte, a passage in the Landwehr line from Hamelin. In the forest south-west of the Gröninger Feld, the forester's lodge Heisenküche was built at the end of the 18th century. It was intended to protect the northern border of the Hamelin city forest.
