Ehrenbreitstein Fortress in Koblenz

You're standing at Ehrenbreitstein Fortress, high on a hill on the east bank of the Rhine. Walk over to the edge and look down. That's where the Moselle flows into the Rhine, with Koblenz on the far side. On the point you'll spot the Deutsches Eck, the monument to Emperor Wilhelm I from 1897. Together, the fortress and the monument were seen as the guard on the Rhine.
