Schloss Stolzenfels
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.
Moselstaustufe
Information centre in the fish pass building dedicated to the river Moselle and fish migrations.
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 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. Rivers were the most important logistic routes until the 20th century. Their possession could decide who won or lost a war.
