Former Kowloon British School is the oldest surviving school building which is constructed for children of overseas parents living in Hong Kong. In 1900, Mr. Ho Tung (later Sir Robert) donated $15,000 to the Government to set up a school in Kowloon. The building was officially opened by the Governor, Blake on 19 April 1902. The school was officially opened as a primary school for some 60 pupils but it was converted to be a secondary school for some 300 students in the mid 1930s.
The building is a typical Victorian structure, but was modified to adapt to local climatic conditions by adding wide verandas, high ceilings and pitched roofs.
The Family Welfare Association and Tsim Sha Tsui Kaifong Association had used the building after the Second World War. It now houses the Antiquities and Monuments Office after restoration. It is "declared monument" since 19 July 1991.
This monument opens 9:00 a.m. - 6:00 p.m. daily but the cache is accessible 24 hours daily.
