The Old Tai O Police Station was built in 1902 to supervise the Tai O area with a main duty of combating pirates prevalent in the neighbouring waters. At the beginning only six or seven policemen were stationed at the police station but by the year 1983 the number of police officers had increased to over 180. In view of the extremely low crime rate in the Tai O area the Station was turned into a patrol post only in 1996. The Station was left vacant since November 2002.
The station, which consists of two 2-storey blocks comprising the main block and the barrack block linked by a footbridge at first floor level, is an excellent example of disciplined services and colonial style architecture with security system throughout the building.
The main block with its Chinese pan-and-roll tiled roof, projecting eaves and arched verandahs has an Italianate Renaissance appearance, whilst the barrack block displays features of the Arts and Crafts architectural style.
