Ahausen is a village in the district of Rotenburg, in Lower Saxony, Germany. Ahausen is administratively part of the collective community of Sottrum.
The Evangelical Lutheran church is the village's landmark. The church was rebuilt in 1637 and again in 1848.
The Ahauser mill with its 9-acre (36,000 m2) mill pond is a popular tourist attraction.
The Coat of Arms symbolizes the local church, the Wümme river and other local streams, and the nearby nature preserve known as "Wolf's Ground" (Wolfsgrund).
Ahausen is located 8 km. (5 miles) southwest of Rotenburg, 35 km. (22 miles) east of Bremen and 70 km. (44 miles) southwest of Hamburg. The Wümme river flows from east to west about 2 km. north of the center of Ahausen.
The first record of the village was in 1226 as "Ouhusen". Then Ahausen belonged to the Prince-Bishopric of Verden, established in 1180. The town was destroyed in the Thirty Years War (1618-1648) by the forces of Count Tilly. In 1648 the Prince-Bishopric was transformed into the Principality of Verden, which was first ruled in personal union by the Swedish Crown - interrupted by a Danish occupation (1712-1715) - and from 1715 on by the Hanoverian Crown. The Kingdom of Hanover incorporated the Principality in a real union and the Princely territory, including Ahausen, became part of the new Stade Region, established in 1823.
