text: The Vogelfluglinie (Danish: Fugleflugtslinjen), an important transport corridor connecting the Danish capital of Copenhagen on the island of Zealand to the second-largest German city of Hamburg via Lübeck, runs across the island. There are currently two tunnels under construction in the region: the Fehmarn Belt Tunnel between Puttgarden on Fehmarn and Rødbyhavn on Lolland, and the Fehmarn Sound Tunnel between Strukkamp (Fehmarn) and Großenbrode (Wagria). The most notable settlements on Fehmarn are Burg auf Fehmarn (Low German: Borg op Fehmarn) and Puttgarden, with the island's ferry port.
  Fehmarn is allegorically represented by the "Goldene Krone im blauen Meer" (Golden Crown in the blue Sea), which can be seen on many flags on the island, making reference to the House of Oldenburg, the Danish royal house.
  History
  Earlier names of the island are Femera, Fimbria, Cimbria parva, and Imbra. As a part of Wagria, it was settled by the Slavic Lechitic tribe of Wagri in the Early Middle Ages. Fehmarn is one of the westernmost places of the former contiguous settlement area of the Slavs, and the westernmost island with a former Slavic settlement. The name of the island itself derives from the Polabian fe more (in the sea), modern v more, and has the same etymological background as Pomerania, deriving from po more, at the sea. Puttgarden is also a Slavic name, deriving from pod gard, which means under the castle (on  Rügen exists a village with the same etymological background, evolving into the modern form Putgarten).
