What is "sylt-ost"

Sylt-Ost (translated, East Sylt) is a former municipality on the island of Sylt, in the district of Nordfriesland, in Schleswig-Holstein, Germany. It used to be the administrative seat of the Amt Landschaft Sylt and a municipality into which a number of villages had been amalgamated in 1970. However, following a referendum in May 2008, Sylt-Ost merged with Westerland and Rantum to form the collective municipality Gemeinde Sylt which was created on 1 January 2009. Since 2009, the seat of the Amt Landschaft Sylt has been in Westerland.
