A lakatlan csatahajósziget, amely régen a világ legsűrűbben lakott települése volt

A drone photo shows Hashima Island (Gunkanjima / Battleship Island) in Nagasaki City, Nagasaki Prefecture, western Japan, on August 13, 2020. The island's most notable features are its abandoned concrete buildings, undisturbed except by nature, and the surrounding sea wall. While the island is a symbol of the rapid industrialization of Japan, it is also a reminder of Japanese war crimes as a site of forced labour prior to and during the Second World War. The 6.3-hectare (16-acre) island was known for its undersea coal mines, established in 1887, which operated during the industrialization of Japan. The island reached a peak population of 5,259 in 1959. In 1974, with the coal reserves nearing depletion, the mine was closed and all of the residents departed soon after, leaving the island effectively abandoned for the following three decades. The coal mine of the island was formally approved as a UNESCO World Heritage Site in July 2015, as part of Japan's Sites of Japan's Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining.
