Sylt
In short
Sylt is the largest of the North Frisian Islands and the northernmost island in Germany. It is located in the North Sea within the state of Schleswig-Holstein.
In plain words
It is a long, thin island famous for its sandy beaches and seaside resorts. Many people visit for holidays, though the island faces challenges from rising sea levels and storms.
A simple example
A tourist might stay in the resort town of Westerland to walk along the 40-kilometre stretch of beach.
Why it matters
The island is a major centre for German tourism and has a unique North Frisian culture. It is also a key site for studying coastal erosion caused by the North Sea.
Easy to mix up
Do not confuse it with Sild, which is the Danish name for the same island.
