Stone beacon hut with suspended metal cage on Tjøme coast

The image shows a small, stone structure with a conical roof, resembling a hut. A long, dark pole extends from the roof, with a metal cage-like object suspended from its end by a chain. The structure is situated on a rocky, flat surface overlooking the sea. In the background, there are islands and the blue ocean under a bright sky with wispy clouds. This is the "Vardehuset" on Verdens Ende, Tjøme, Norway. There are no people visible in the frame.
