The Rhine Valley between the cities of Koblenz and Rüdesheim is one of the most visited tourist destinations in Europe. Breathtaking views, over 20 castles, 
the most impressive of which are Marksburg and Liebenstein. 
Koblenz is an old town with many well-preserved historical sights, such as the spectacular Ehrenbreitstein Fortress and the neoclassical Koblenz Schloss. 
The cathedral in the city of Worms is from the 11th century. With its four towers and twin domes, this spectacular old building ranks with the cathedrals of Speyer and Mainz as one 
of the finest achievements of the High Romanesque style.
In the heart of the UNESCO World Heritage Site of the Rhine Valley, 
the picturesque old town of Braubach. In the center of town, perched high atop a hill that towers over the surrounding area, sits Schloss Marksburg, built in 1117 and 
the only hilltop castle in the Rhine Valley to survive intact.
