Alte Schwentine

The Alte Schwentine is a river in the region of Holstein in North Germany. Its different sections are also known as the Bornau, Depenau, Kührener Au, Postau and Mühlenau.

Course

It rises near Bornhöved on the hill of Grimmelsberg by the road from Bornhöved to Tarbek in a meadow and in the mill pond of Bornhöved. Initially, it flows through the Bornhöveder See and from there to the Schmalensee. From there it flows past former Slavic Belauburg into the Belauer See. Behind the lake it passes the Perdöl Mill, an old water mill, and flows into the Stolper See in an old carr wood at Perdöl Manor House. It leaves the Stolper See at Depenau Mill and flows past Depenau Moor towards Depenau Manor House. Beyond the manor house the river is also called the Kühren Au and meanders through meadows to the west of the town of Preetz located on the Postsee lake. Here it joins the Schwentine, which rises on the Bungsberg and empties into the Kiel Fjord in the Baltic Sea.
Between Postsee and Schwentine the names Postau or Mühlenau are used.

Names

This use of different names came about as a result of a mistake by the cartographer, Caspar Danckwerth, who, in 1652, gave the real Schwentine — associated with Sventanafeld, the field of battle at the Battle of Bornhöved, different names such as the Bornhöved Bornau, Depenau, Kühren Au and Mühlenau. As a result the Bungsberg Schwentine was declared to be the real Schwentine.

Limes

A section of the Limes Saxoniae, the fortified border rampart between Saxons and Wends, which was built by the Emperor Charlemagne, ran along the chain of lakes on the Old Schwentine.
