From a vantage point 75 feet (about 23 metres) over Singapore’s former harbour, officers with the Harbour Division of the Preventive Branch of the Department of Customs and Excise (which later became Singapore Customs), stood watch over the Inner Roads of the harbour for more than three decades. The vantage point, a panoramic lookout tower that we still today, was part of the Customs Harbour Branch Building built over an L-shaped pier along the waterfront at the end of Collyer Quay. The building and pier, built at a cost of S$1.8 million, was completed in October 1969. The complex housed the 300 strong force of the then Harbour Division, as well as provided berths and maintenance facilities (which included a slipway) for some 35 launches and speedboats of the Division when it first opened. The building also provided cargo examination facilities and its construction allowed the Division to move from its somewhat makeshift premises in a godown in Telok Ayer Basin.
While 75 feet in the context of what now surrounds the former Customs complex, the tower allowed customs officers to keep a round-the-clock watch over the harbour for small boats attempting to sneak dutiable goods into Singapore. The octagonal shaped and fully air-conditioned watch tower which is supported by a cylindrical base provided a panoramic view which extended beyond the Inner Roads to the mouth of the Singapore River, the Geylang River and Tanjong Rhu. Officers spotting a suspicious boat could then alert their colleagues manning the speedboats which were on standby by the pier who would then head out to intercept the suspicious boat.
Use for the building and the pier in its intended role ended with the construction of the Marina Barrage which cut what were the Inner Roads of the old harbour off from the sea and the building then under the Maritime and Port Authority’s charge was passed over to the Singapore Land Authority in 2006. Customs House was given conservation status in 2007 and was reopened as a dining destination under the management of Fullerton Heritage, which also manages the former Clifford Pier and the Fullerton Hotel. The tower itself is however disused and remains inaccessible to the general public.
