The Kowloon Walled City was once the most densely built places on Earth, with hundreds of houses stacked upon each other creating a town that was solely encompassed by concrete. In the 90s the city was demolished and rebuilt upon, but you can still see the old cities mark laid on Hong Kong.
The Hong Kong photographer Andy Yeung has captured just this, with his iconic drone photos that show the city in a different light. The nine photos shot almost make you feel like you have been integrated in to a video game IRL.
