Kowloon Walled City, established on the remnants of a military fort in British Hong Kong, peaked in 1989 with over 35,000 residents in just six and a half acres, making it the most densely populated place on Earth. The area was characterized by chaotic architecture, interconnected buildings, and narrow alleyways, functioning as a vibrant hub of illegal trading and organized crime despite being classified as a slum. Architect Sluda Builds has recreated Kowloon Walled City in Minecraft, accurately positioning buildings and capturing various architectural styles, but the virtual representation lacks the vibrant life and human experiences that defined the original Walled City.
