This week's lighthouse actually doesn't work as a lighthouse anymore. It's just for show in Malmö, Sweden. But it's good-looking, and it's also octagonal, which makes it a bit unusual.
Here's what Lighthouses of Sweden (Scania) says about it:
1878. Inactive since 1983 (a decorative light is displayed). 20 m (66 ft) octagonal cast iron tower with lantern and gallery, mounted on an octagonal stone base. Tower painted white with two narrow red horizontal bands; the lantern dome is also red.Three shots from various angles.
