kowloon walled city

The Kowloon Walled City was a densely populated enclave in British Hong Kong. As the population of the enclave grew during the Opium Wars, new buildings and passageways appeared. Soon, the structure that began as a Chinese military fort became something of a living organism -- growing and evolving as residents and business owners added to the structure to suit their needs.
