The Electoral Palace in Koblenz, was the residence of the last Archbishop and Elector of Trier, Clemens Wenceslaus of Saxony, who commissioned the building in the late 18th century. In the mid-19th century, the Prussian Crown Prince had his official residence there during his years as military governor of the Rhine Province and the Province of Westphalia. It now houses various offices of the federal government.

This is a nice little fountain near the town hall. You should stand three steps in front of the fountain and in front of the figure's face. Wait there three minutes. What then happens should bring fortune.
This spot (the name means German Corner in German) is where the Mosel River meets the Rhine River. The tip of the park is shaped like a ship's prow, overlooked by an enormous equestrian statue of Kaiser Wilhelm mounted on an equally-huge stone base that you can climb for a great view of the rivers and opposite shore castle/fort. Not far from the German Corner, you can catch a little sightseeing train which will drive around & point out some of the interesting things about Koblenz.
This is a big military castle/fort in good condition. From there you have a good view over Koblenz. There is also one of the museum of Koblenz. It is located on the other side of the Rhine.

Information centre in the fish pass building dedicated to the river Moselle and fish migrations.
This is a big military museum. It is located on the other side of the Mosel. In the past Koblenz was an important strategic military area. On every side of the rivers were military castles/forts.
