On the site of today’s Kowloon Walled City Park stood until 1994 the Walled City. It had a population density of an unbelievable 1 million people per km² and was completely outside the rule of HK law. It housed schools, textile and food factories, hundreds of illegal dentists and maybe thousands of triads. The Anarchist’s Nirvana was torn down because the Walled City had become a huge fire hazard and the HK government wanted to finally be able to raise taxes on the income of its residents.
