500px provided description: This is what you can see from the sea when approaching the Gunkanjima island. It used to be a coal mining island but now it's just some ruins in the middle of the ocean. It was the most densely populated city in the world, and if my map-reading is good those were the living quarters. [#island ,#building ,#ghost ,#industrial ,#mine ,#ruins ,#nagasaki ,#gunkanjima]
