Kemper Werth

The Kemper Werth (also known as auf dem Schänzchen and historically as the Pfaffenmütze) is a promontory in the Rhine at the mouth of the River Sieg, in the northeast of Bonn, in Germany.

The Sieg originally flowed into the Rhine through a delta, entering the river at an angle opposite the northern end of the two islands of the Kemper Werth.

In 1620, the islands were occupied and a fort constructed by forces of the States General of the Netherlands, in one of several pre-emptive strikes against the Spanish and in support of the claim of the Elector of Brandenburg, Georg Wilhelm, to the territories of Jülich-Berg during the Eighty Years' War.

[9] The Kemper Werth is part of the Naturschutzgebiet Siegaue,[10] which encompasses 150 hectares (370 acres) around the mouth of the Sieg, including former branches of the river and some oxbow lakes.

There are plans to restore it to a more natural state, including reduction of nitrogen in the Sieg to encourage a greater variety of plant growth, gradual replacement particularly on the Kemper Werth of the poplars and other introduced species with a mix of native trees,[9] and reversal of measures taken to shore up river banks.
