Situated north of the Szczecin Lagoon, Usedom Island has been divided between Poland and Germany since 1945. It is the second biggest Pomeranian island after Rügen, and it boasts an incredibly rich history. The first settlements date back to the Stone Age, when the area was inhabited by Germanic tribes. Archeologists found 11 graves from that time period, as well as over 100 villages form the Bronze Age. If ancient history is not your gem, don’t worry. You can simply relax on the 42km-long beach.
