Abandoned Russian Polar Nuclear Lighthouse

Russian Northern coast is a vast territory lays for a few thousand of miles and all this coastline is inside the Polar Circle. Long polar winters mean no daylight at all, just one day changes another without any sign of the Sun rising above the horizon. There is only polar night for 120 days a year.

So, the Communist Party of the Soviet Union decided to build a chain of lighthouses to guide ships finding their way in the dark polar night across uninhabited shores of the Soviet Russian Empire. So it has been done and a series of such lighthouses has been erected. However, these have been abandoned due to signs of radioactivity.
