Kowloon Walled City - Baseball Tee
Kowloon Walled City was basically the world's biggest squat. The people living there managed to get by with a single water tap for an estimated 33,000 residents. the population density was 1.255 million people per square kilometre (3.25 million per square mile). That's fucking nuts.
Apart from all of that, Kowloon Walled City brought us some super rad photography and stories. I think they made a Call of Duty level out of it too.
