We went to Kaiserswerth to see a castle built by Emperor Friedrich Barbarosa. The castle was built in 1184; that’s more than 500 years before the very, very old house! The Emperor Barbarosa built it on an island in the big Rhine River. Then one day warriors from the country of France came and knocked it all down. The German people built it again. But guess what? The people from France came back many years later and knocked it all down again! So it’s kind of a wreck. Here is what it looks like.
