Fuerteventura, Spain, January 2023 - Jan & Jan-Jan's Rejseklubben

Villa Winter (Spanish: Casa de los Winter) is a villa situated in a remote location of the southwestern part of the island of Fuerteventura, Canary Islands, near the village of Cofete on the Jandía peninsula. The villa was designed and built by Gustav Winter, a reclusive German engineer, born in 1893 in the Black Forest region of Germany. The villa has two floors and a basement, a balcony in the front, and a tower in the northeastern corner, with a 360-degree view.
The villa is the subject of several conspiracy theories, often involving Nazis. The main theory involves the fact that the villa had a tower with an electric lantern installed in its turret, similar to a lighthouse, and that it was used to signal German U-boats. The tower has a large fuse box installed on the wall. However, in an interview shortly before she died, Winter's widow said that the villa was built purely to exploit the agricultural potential of the area. There are tunnels and rooms in the basement under the house, some built with walls 1.4 metres (4 ft 7 in) thick, and with arched ceilings, said to be effective at resisting explosions. The current resident and caretaker, Pedro Fumero, who was interviewed in a documentary, claimed to have played in the basement as a child, and saw shackles there in a windowless room just wide enough for a person's arms to be affixed to opposite walls. He said that he had investigated 1.3 metres (4 ft 3 in) below the house, but was forbidden by local authorities to excavate what he suspected were hidden cavities. It was claimed that the remnants of an air strip, similar to the one built by Winter elsewhere on the island, could be seen from above in front of the house.
