You've probably heard of Hong Kong's fabled Kowloon Walled City, the massive, densely-populated ramshackle metropolis run by the Triads that once stood on the outside of HK city-limits.

While the largely ungoverned city-scape has been subject of many books and photo-essays, video footage within the complex is rare. Before it was eventually demolished in 1994, the city housed some 50,000 residents. The average rent was $35 HK per month for a room.

Check out the rare glimpse of day-to-day life within the walled city below.
