The German empress "Kaiserin-Augusta" from "Sachsen-Weimar-Eisenach" engaged the prussian horticulturists "Peter-Joseph Lenné" and "Hermann Fürst von Pückler-Muskau" to arrange and design the left rhine riverbank in Koblenz. Many art monuments edged the 3,5 kilomerters long promenade, but most of them were destroyed in World War II...

Castle Burg Klopp in Bingen
Castle Clopp was built in the 13th century to strengthen the toll barrier together with the opposite castle "Ehrenfels" and the later built "Mäuseturm" (Mouse Tower). After the destruction in the 30-years-war it was rebuilt 1653, and then again destroyed by the french troops in 1689. First Ludwig Maria Cron rebuilt it 1853 and then architect Eberhard Soherr 1875 - 1879. Today castle Burg Klopp accommodates the municipality of Bingen.

The "Binger Mäuseturm" (mouse tower) was built in the early 14th century as a toll- and watchtower on a small island in the rhine to strengthen the toll system in connection with castle "Ehrenfels". It was destroyed during the 30-years-war and in 1689 by the french. The prussian king "Friedrich Wilhelm IV." rebuilt the mouse tower in the newgothic style during the years 1856 to 1858. Until 1974 it was used as a signal tower for the ships passing the narrow and dangerous "Binger Loch". The legend has it that the stone-hearted bishop Hatto I. from Mainz escaped to his tower and was devoured by thousands of mice.
During the period of "Rhine-romanticism" the mouse tower inspired famous writers as Clemens Brentano, Victor Hugo and Ferdinand Freiliggrath.

Castle Ruin Fürstenberg above Rheindiebach
Fürstenberg was built from "Erzbischof Engelbert von Berg" to protect the cologne properties around Bacharach. During the 30-years-war Fürstenberg was captured first by the spanish in 1620 and then by the swedish in 1632. Finally the french destroyed Fürstenberg 1689 as well as most of the other castles on the left side of the river. But unlike most of the other castles, Fürstenberg was not rebuilt in the 19th century, so that today you can see some original medieval remains.

Castle Ruin Stahlberg is situated a a side valley above Bacharach-Steeg.
Probably built in the 12th century by the "Erzbischöfe" from Cologne to secure their properties. Both castles, "Fürstenberg" and "Stahlberg" were released to the "Wittelsbacher Pfalzgrafen" in 1243. During the 30-years-war the castle was damaged by swedish troops in 1631. Later, in 1689 Stahlberg was destroyed completely by the french troops during the "Pfälzische Erbfolgekrieg".
