The world's most was demolished over 30 years ago. Kowloon Walled City was home to 35,000 residents that were packed into a territory of 26,000 square metres. The neighbourhood was initally established in 1898. However, it was only following the end of the Japanese occupation of during that the city's population took a dramatic turn.

Kowloon Walled City saw an influx of residents, but having no official government, the city was driven by crime. The anarchic nature of the area allowed criminals to take advantage, with many of them trading illegal products from narcotics to dog meat. That was the story of the city for the next 20 years.

Between the 1950s and 1970s, the walled city was ruled by local triad gangs and suffered from prostitution, gambling, and drug abuse.

Despite the extremely severe crime levels and chaos across the city, Hong Kong police barely intervened, making the city an absolute haven for criminal activity to continue and thrive.

That was until a shift happened in 1973 and 1974. The police carried out over 3,500 raids which resulted in over 2,500 arrests and the seizing of more than 1,800 kilograms of drugs.

The raid continued, and with the backing and support from residents, violent crime and drug use across the city began to decline. A decade later, the district police commander declared Kowloon Walled City's crime levels to be under control.

The population continued to surge, to the point where developper had to construct homes on top of older properties. However, by the 1980s, a height restriction of 13 to 14 storeys was imposed.

Residents did not experience the best living conditions. It was rare that any of the city's streets caught any light as the sun hardly reached lower levels.

In fact, the quality of life in Kowloon Walled City was much worse than the rest of Hong Kong. Yet that did not stop the locals making the most out of life. Many of the despite the crime and bad living conditions, managed to live peacefully amongst the enclosed city, and even went on to start their own successful small businesses.

Shortly after, in 1984, the decision for the city to be demolished was made, and 10 years later it was competely gone. While residents of the walled city were offered $350 million (approx. £260 million) in compensation, many were unsatisfied and therefore had to be forced out of their homes.

In 1995, the city was transformed into the Kowloon Walled City Park under a £7 million project. The park divided into eight landscapes features artefacts from the walled city, and has paths named after the old streets and buildings.
