The Old Tai Po Police Station was built in 1899 as the first police station and the Police Headquarters in the New Territories, and is the oldest surviving police station in the New Territories. During the Japanese Occupation Period, the police station was left vacant, and its windows, doors, wooden floor and anything usable were looted by nearby residents. It resumed as police station after the occupation period until 1987. The site was then changed to house the Hong Kong Police Force New Territories North Regional Crime Prevention Office and used as temporary accommodation and offices for the Marine Police North Division until 2006 . It has been revitalised into the Green Hub through the Revitalising Historic Buildings Through Partnership Scheme to promote conservation and sustainable living.
The Old Tai Po Police Station comprises three single-storey buildings in Utilitarian style, namely the Main Building, Staff Quarters Block and Canteen Block. The spacious and flat lawn links the three buildings together. The original architectural features have generally retained much of its original authentic appearance, such as the Dutch gables, ornamental window arches, window sills and the fireplaces. The external features, such as the guard house and octagonal well near the entrance and the brick incinerator in the lawn remain in very good condition. Most of the architectural features are still visible in the site despite internal refurbishment, alterations and additions made for operational requirements over the past 120 years.
Old Tai Po Police Station was declared a monument in 2021.
