Island of Sylt by Jutland Peninsula, Denmark and Germany
The west coast of the Jutland Peninsula, along the Wadden Sea, is marked by many inlets and nearby islands. Of particular interest is the T-shaped island of Sylt, below center. An imaginary line running from the island eastward across the peninsula would delineate the border between the countries of Denmark (above) and Germany (below).
Sylt, belonging to Germany’s North Frisian Islands, is well known for the distinctive shape of its shoreline. With 99.14 km², Sylt is the fourth-largest German island and the largest North Sea island. Sylt is situated at 9 to 16 km off the mainland.
The island’s shape has constantly shifted over time, a process which is still ongoing today. It is frequently covered by the media in connection with its exposed situation in the North Sea and its ongoing loss of land during storm tides.
Today, Sylt extends for 38 km in a north-south direction and on its northern peak at Königshafen is only 320 m wide. Its widest distance, from the town of Westerland in the west to the eastern Nössespitze near Morsum, measures 12.6 km. On the western and northwestern shore a 40 km sand beach is located. Much of the Wadden Sea east of Sylt belongs to the Schleswig-Holstein Wadden Sea National Park and mostly falls dry during low tide.
