What is "warnau"

Warnau is a municipality in the district of Plön, in Schleswig-Holstein, Germany.

The Warnau is a right-bank tributary of the River Böhme in North Germany and is part of the Weser basin. It is about long and has a catchment area of , mostly in the district of Soltau-Fallingbostel in Lower Saxony.

The Warnau rises in the area of Behningen near Neuenkirchen, flows generally southwards from the village of Ottingen, passes Ahrsen, Jarlingen, Benefeld and Cordingen and discharges into the Böhme south of Borg in the municipality of Bomlitz. Near Ottingen the Warnau is also called the Schneebach, which comes from the fact that the stream once formed the border ( Low German: Sneede) between the Bishopric of Verden and the Duchy of Lüneburg, now the district boundary between Soltau-Fallingbostel and Rotenburg. Between Cordingen and Benefeld it forms a charming, narrow, wooded valley with a restored mill, the Cordinger Mühle, that hosts events. Downstream to its mouth the meadow valley is accompanied on one side by a pictureseque bluff with narrow footpath. At its southern end the path meets the Bomlitz Archaeological Trail (Archäologischen Wanderpfad Bomlitz), which runs through a Bronze Age burial site on a rounded hilltop in the recreation area of Eibia-Lohheide and continues south to Vogelparkstraße to the impressive system of ramparts belonging to the Old Saxon fort of Hünenburg at the confluence of the Warnau and the Böhme. The site is linked by legend to the founding of the oldest Lüneburg Heath's monasteries, the nearby Walsrode Abbey.

The Walsrode–Visselhövede railway follows the Warnau valley, which has now been dismantled north of Cordingen (with its old station of Jarlingen). The section south of Cordingen is now the Bomlitz–Walsrode railway which is worked by goods trains to the factory of Wolff and the Walsrode Industrial Park in Bomlitz. This line crosses the Warnau on a high bridge between Cordingen and Benefeld.
