Sham Shui Po Barracks was a British Army establishment built in the 1920s and was originally known as Hankow Barracks and Nanking Barracks. It was built to allow troops to be garrisoned closer to the New Territories, which was acquired by the British some 20 years earlier. The base was bounded by what is now Fuk Wa Street to the east by Yen Chow Street and to the west by Tonkin Street and Camp Street.
During WW2 this was used by the Japanese as a POW Camp for British, Indian and Canadian soldiers. In the late 1970s and early 1980s the camp was used to house Vietnamese refugees.
In the early 1990s the whole area was redeveloped, and nothing remains of these old barracks.
