Sylt

Sylt is a German island in the Frisian archipelago in the North Sea. It's known for its long beaches, resorts and the Wadden Sea mudflats on the eastern side. The 1700s Old Frisian House has a thatched roof and exhibits about pre-20th-century island life. Denghoog is a neolithic passage grave filled with giant stone boulders. To the north, Naturgewalten is an interactive ecological museum with multimedia displays.
