Europe - what are the must see places to visit?

If you're in Germany, here are a couple of possibilities, but they're not particularly cheerful:1.� Modlareuth.� It's a small village located north of Hof, in northern Bavaria.� Its claim to fame is that back when there were two Germanys, the border ran down the middle of the village.� It was known as "Little Berlin."� They've saved some pieces of the old border fortifications for a museum.2.� Dachau.� This is the site of a Nazi concentration camp, which has been preserved as a museum.� It's northwest of Munich.For something a bit more uplifting:3.� Bayreuth.� This city in northern Bavaria was the home of the composer Richard Wagner, and they celebrate his music every summer.
