Aniva Rock Lighthouse – Sakhalinskaya Oblast, Russia
The Aniva Lighthouse, also known as the Sakhalin Lighthouse located in the Sakhalinskaya Oblast, Russia. This lighthouse is one of many that are part of the Polar Nuclear Lighthouses, this one being closer to Japan than anything. They were put along the coast of Russia to help aid in the passage of ships because of Polar Night.
Since they could not be crewed or supplied constantly these autonomous nuclear-powered lighthouses were erected. Many think these are radioactive because they were nuclear powered, but I cannot find a clear answer for this. Regardless, this particular lighthouse cut into the stone looks like something from a fairy tale.
