The castle "Wolfsburg" was first mentioned in 1302 in a document as the domicile of the noble lineage of Bartensleben. Originally a keep next to the Aller, it was protected by a moat some centuries later. In 1372, the first documentary reference to the Burg Neuhaus ("castle of Neuhaus") near Wolfsburg appeared. After the extinction of the Bartensleben line in 1742, the property and its Schloss Wolfsburg ("Wolfsburg Castle") passed on to the Counts of Schulenburg. The communal manor was an important employer for the nearby settlements "Rothenfelde" and "Heßlingen".
