Nowadays, you can easily find a calm oasis along with touches of spirituality in Kowloon. Let's start at the serene Kowloon Walled City Park, located at Tung Tau Tsuen and Tung Tsing Roads, and built on one of the most historic sites in the region. As early as the 15th century, forts and other buildings were established here for the sake of security by the mainland Chinese. A small site became a bigger one and after the New Territories were leased to the British in 1898, it is said that China continued to claim authority over the Walled City but did not administer to its growing needs. The tall tenement buildings that developed here on 6 ½ acres over the second half of the 20th century gave rise to one of the most notorious ghettos on the planet.
