This is a quite iconic lighthouse at the German north-sea coast in the state of Schleswig-Holstein. It’s used in quite a lot of commercials. When used in commercials, there is usually not so much landscape in the frame.
Nowadays, the two houses beside the lighthouse are used for nature preservation purposes. Huge portions of the Wadden Sea are part of the National Park German Wadden Sea, founded in 1985. That National Park covers the costs of the North Sea of the German states Lower Saxony, Hamburg (since 2011), and Schleswig-Holstein and continues in Denmark (since 2014).
