The Grönegau (also Graingau) is the historic regional name for one of the many Saxon Gaus that have survived to the present day.
[2] The Grönegau is a region that, for the most part, covers the same area as that of the present borough of Melle in the district of Osnabrück in the German state of Lower Saxony.
From around 800 to the 12th century the old southern Gau border probably ran from Borgholzhausen and Halle to Bünde and Spenge in the east.
Subsequently, it lost parts of the Grönegau of the Early Middle Ages, including Halle, Borgholzhausen and Borgloh.
