Hashima Island is also called Gunkajima (Battleship Island) because of its shape.
This island close to Nagasaki in the south of Japan was exploited for undersea coal and people lived here in harsh conditions. In its heyday it was the most densely populated area in the world.
During WWII it was used as a forced labour camp.
When the mine depleted in 1974, the inhabitants only had 1 month to leave the island.
It became abandoned and slowly became a famous landmark.
The island featured in the James Bond movie Skyfall and in 2015 it became a UNESCO World Heritage Site.
