Kowloon Walled City
Britain quickly went back on this unofficial part of the agreement, attacking Kowloon Walled City in 1899, only to find it deserted. They did nothing with it, or the outpost, and thus posed the question of Kowloon Walled City's ownership squarely up in the air. The outpost consisted of a yamen, as well as buildings which grew into low-lying, densely packed neighbourhoods from the 1890s to 1940s.
