Kowloon Walled City: Life in the City of Darkness
It's 20 years since demolition of Kowloon Walled City began, but former residents hold fond memories of the overcrowded slum they called home

It was called a lawless twilight zone by some and the world's most overcrowded squat by others. But to many, the Kowloon Walled City was simply home.

A 2.7-hectare enclave of opium parlours, whorehouses and gambling dens run by triads, it was a place where police, health inspectors and even tax collectors feared to tread.
In Cantonese, it was known as the City of Darkness.
But though it may have been a fetid slum, crawling with rats and dripping with sewage, it was stoutly defended to the last by those who lived there, as well as an unlikely ensemble of Chinese shopkeepers, faith healers and self-taught dentists.
It was once thought to be the most densely populated place on earth, with 35,000 people crammed into a few tiny apartment blocks and more than 300 interconnected high-rise buildings, all constructed without contributions from a single architect.
