Trelleborg is a sleepy port town in southern Sweden, best known for its medieval fortress. The imposing structure was once a strategic stronghold, guarding the country’s southern coast from Danish invaders. These days, Trelleborg is a popular stop for cruise ships, and the fortress is open to visitors. The town is also home to a lively market, where you can buy everything from smoked herring to traditional handicrafts. In the summer, the locals head to the beach for a swim or a game of beach volleyball. If you’re looking for a quiet place to relax, Trelleborg is a great choice – just don’t expect too much nightlife.
