context_page_description: Wölpe is a river of Lower Saxony, Germany. It is about 17 km long and a left tributary of the Alpe.
  The Wölpe has its source in a depression southeast of Erichshagen-Wölpe, a village in the borough of Nienburg and flows towards the northeast. In front of Rethem the Weiße Graben links the Wölpe with the Alpe. The Alpe-Wolpe-Umfluter then discharges into the Aller near Wohlendorf in the borough of Rethem. The waterway has been considerably straightened. It flows through woods, grassland and cultivated fields. According to the 2000 Water Quality Chart issued by the NLWKN it is critically polluted throughout.
context_section_description: At about 0.8 kilometres (0.5 mi) from the source near the Nienburg village of Erichshagen-Wölpe the Wölpe flows by the mound on which the former castle of the counts of Wölpe stood. During the Middle Ages the waterway was widened into a moat for the security of the fortified position and flowed around the castle built in the 12th century. After the destruction of the site in the 17th century the castle moat and the Wölpe were filled with rubble.
  About 4 km (2.5 mi) further on near Heemsen the Wölpe flows into the wood by the site of the 9th century Brunsburg castle. Here, too, the stream was probably used as part of the defences.
