Japanese researchers created an incredibly detailed illustrated cross-section of Hong Kong’s notoriously overcrowded Kowloon Walled City (previously) shortly before the enclave was torn down in 1993. The map can be viewed in full size in the book, Large Illustrated Kowloon City, by Kowloon City Expedition, Kazumi Terasawa, and H. Kani.
