Middle Rhine"Between Bingen and Bonn, Germany, the river Rhine flows as the Middle Rhine (German: Mittelrhein) through the Rhine Gorge, a formation created by erosion, which happened at about the same rate as an uplift in the region, leaving the river at about its original level, and the surrounding lands raised. This gorge is quite deep, about 130 metres (430 ft) from the top of the rocks down to the average water-line. The "Middle Rhine" is one of four sections (High Rhine, Upper Rhine, Middle Rhine, Lower Rhine) of the river between Lake Constance and the North Sea. The upper half of the Middle Rhine (Rhine Gorge) from Bingen (Rhine-kilometer 526) to Koblenz (Rhine-kilometer 593) is a UNESCO World Heritage Site (2002) with more than 40 castles and fortresses from the Middle Ages and many wine-villages. The lower half from Koblenz (Rhine-kilometer 593) to Bonn (Rhine-kilometer 655) is famous for the formerly volcanic Siebengebirge with the Drachenfels volcano. Both parts together are known as "the romantic Rhine"." - (en.wikipedia.org 21.09.2020) Germany
