The strange labyrinth "Trojeborg" can be seen on the southern part of the island. The labyrinth is classified as an ancient site, but no one knows who built it or how old it is. It was already noted during Carl von Linné's visit in 1741. A walk through the entire labyrinth is said to bring good luck. And if you start the walk without completing the labyrinth until you are outside again, it is said that you are brought by misfortune!
