Hong Kong's roster of surviving historic police stations is short. The Old Aberdeen Police Station is the second oldest still standing, built in 1891 as a replacement for an even earlier station that had become inadequate for the growing community of the Southern District. Only the Old Stanley Police Station, dating to an earlier period, holds a longer claim.

The 1891 building was not built to be a monument. It was built because Aberdeen's population was growing and the existing law enforcement presence was insufficient. The station's purpose was practical and immediate: strengthen order in a community of fishermen, traders, and boat dwellers whose lives played out as much on the water as on land.

The December 1941 Japanese assault on Hong Kong came quickly and hit widely. Aberdeen, on the southern side of Hong Kong Island, did not escape. The Old Aberdeen Police Station was bombed and badly damaged during the Second World War — a violence visited on a building that had stood for fifty years through the ordinary challenges of colonial policing.

The station continued operating after the war but closed in 1969, when a new police station opened on Wong Chuk Hang Road. Rather than demolish the 1891 building, the government found new uses for it over the following decades: a detective training school from 1969 to 1980, the Marine Police Training School from 1979 to 1982, and the Marine South Station from 1982 to 1986. The building accumulated purposes like a vessel accumulates barnacles — each leaving a mark, none quite fitting the original design.

The station's architecture repays close attention. It was built in Neo-Classical Colonial style with Arts and Crafts influences — a combination typical of late Victorian institutional buildings in Hong Kong, where colonial design conventions met local materials and tropical climate requirements. The main building is a rectangular two-storey structure faced in red Canton brickwork, with open front verandahs that provide shade and circulation.

Granite appears throughout: in the string courses that run horizontally across the facade, in the moulded cornices, in the column bases and capitals of the verandah, and in the cills and lintels of the windows. The narrow strips of granite flanking the windows have been noted to resemble the vertical format of Chinese couplets — an accidental or intentional echo of local visual culture in a building otherwise firmly rooted in colonial convention. Original casement windows, metal balustrades, and sun baffles remain intact. The rear elevation is simpler, with verandahs roofed in Chinese tiles rather than the more formal treatment of the front.

When the Old Aberdeen Police Station was listed as a Grade II historic building in 2009, it had already found a new life. The building is now used as the Warehouse Teenage Club, a youth facility that has given the old station a population its original builders could not have imagined: teenagers from Aberdeen and the surrounding neighbourhoods, coming in off streets that bear very little resemblance to the nineteenth-century fishing town that made the station necessary.

The two ancillary buildings flanking the main structure are also single-storey, built in a simplified version of the same red-brick style, with stone dressings, extended verandahs, and Chinese tiled pitched roofs. Their original doors, windows, and chimney stacks remain. The whole complex, despite its eventful history, retains a coherence that makes the 1891 date feel present rather than merely historical.
