The nuclear lighthouses built by the Soviets in the Arctic
built by soviets, powered by nuclear RTGs, abandoned for decades — they really said 'who needs maintenance'
The Northern Sea Route goes for 5600km from the Kara Sea to the Bering Strait, connecting Western Russia to the Far Eastern territories. In the 1930s, the USSR started building hundreds of lighthouses along this Arctic route. With no keepers, and no other form of electricity available they would run on nuclear energy.
