Let's have a thread about abandoned stuff.
If you find something valuable in those places, are they yours or do they belong to the country?
Once the most densely populated place in the world, this tiny island off the coast of Nagasaki is now a ghost town that’s been completely uninhabited for more than forty years. Gunkanjima was developed by the Mitsubishi Corporation in the early 1900s, which believed—correctly—that the island was sitting on a rich submarine coal deposit. By 1941, the tiny island was producing 400,000 tonnes of coal per year, powering Japan’s industrial expansion. A city grew up around it so dense it inspired the nickname “island without green.”
Disney’s abandoned animal island was almost the coolest attraction ever. Disney opened it as a lush zoological park as the island was home to a number of exotic animals. When the attraction was closed in 1999, the remaining animals were moved to Disney World’s new Animal Kingdom resort, yet the island was simply left to nature, its buildings deteriorating.
Today, the island remains abandoned and off-limits. However some brave urban explorers have managed to infiltrate the island take pictures of what remains. Disney has threatened to ban these adventurers from all Disney properties just for setting foot on Discovery Island, making the whole kingdom seem a little less than magic.
