Europe is home to three things: people who can drink beer and not get fat, house music, and hostels. If you've been planning a trip to Denmark to find the Williamsburg of Copenhagen, but weren't quite sure about the hostel landscape, you're about get super stupid lucky, you silly hipster.

Germany's largest building is a six-story, four-kilometer Nazi-built resort called Prora, located on an island in the Baltic Sea. Originally called "Kraft durch Freude" (Strength Through Joy), it's big enough to house 20,000 people. It was supposed to be even bigger, but World War II disrupted its construction. The building languished mostly unused until three and a half years ago, when a youth hostel moved in. I sense a Hostel sequel coming on.
