Former long wave transmitter station Radio Kootwijk was used during the early 20th century as the main communication relay between the Netherlands and Dutch East Indies. The art-deco building designed by architect Julius Luthmann is also called ‘the cathedral’.
Now abandoned the building still stands in the middle of Dutch moorland, and is somewhat tricky to find. The main building is now used as an exhibition hall. The building was also used in the Hollywood movie ‘Mindhunters’.
