💙🐦⬛The Rantumbecken is an almost 600-hectare water basin in Rantum🧭, which was enclosed by a dike at the end of the 1930s to maintain a constant water level for the originally planned seaplane airport. However, the Rantumbecken was never used as a seaplane airport. A seabird sanctuary was established on the newly gained natural area🐦⬛, which attracts ornithologists from all over today. 🐦⬛💙The Rantumbecken is now one of the most species-rich bird sanctuaries in Northern Germany, where more than 50 bird species can be admired during breeding and resting🐦⬛. Especially during bird migration, thousands of birds can be observed in huge flocks at high tide🐦⬛🐦⬛🐦⬛🐦⬛👌🏼.

Wide sky, wide sea. In the south of Sylt you can walk for miles along the dam that separates the Rantum Basin (a brackish water lake) from the North Sea. It was originally built in 1936/37 on behalf of the Wehrmacht - it was intended to serve as an air base for naval aviation for the Luftwaffe. Today the Rantum Basin is a valuable nature reserve.
