At its height in the 1990s, Kowloon Walled City in Hong Kong housed about 50,000 people. Its population is unremarkable for small cities, but what set Kowloon apart from others of its size was its density. Spanning only 2.6 hectares, the tiny enclave contained 1,255,000 people per square kilometer, making it the densest city in the world.
Kowloon was built as a small military fort around the turn of the 20th century. When the Chinese and English governments abandoned it after World War II, the area attracted refugees and people in search of affordable housing. With no single architect, the urban center continued to grow as people stacked buildings on top of one another and tucked new structures in between existing ones to accommodate the growing population without expanding beyond the original fort’s border.
With only a small pocket of community space at the center, Kowloon quickly morphed into a labyrinth of shops, services, and apartments connected by narrow stairs and passageways through the buildings. Rather than navigate the city through alleys and streets, residents traversed the structures using slim corridors that always seemed to morph, an experience that caused many to refer to Kowloon as “a living organism.”
The city devolved into a slum with crime and poor living conditions and was razed in 1994. Before demolition, though, a team of Japanese researchers meticulously documented the architectural marvel, which had become a sort of cyberpunk icon that even inspired a gritty arcade as tribute.
