Inside fortress city: Amazing images from the lawless Hong Kong slum, once home to 30,000 and one of the most densely populated place on earth

The dystopian Kowloon Walled City, an overcrowded slum in Hong Kong, was home to more than 30,000 residents, including families, gang members and drug addicts, before it was finally demolished in 1994.

The settlement was a cluster of more than 300 high-rise buildings that were blighted by poverty, gangs, drugs, poor sanitation and inadequate services.

 These remarkable photos, showing everything from children playing on rooftops to heroin addicts shooting up on the street, reveal what life was like within the six-acre site.
