An area of Singapore that still has much history buried under it is the area where the former British Naval Base was. Under parts of the former base, which covered an area stretching from the Causeway in Woodlands to what is today Sembawang Park, lies several underground structures, one of which is a the so-called Attap Valley bunker that has recently been brought to light.
The bunker, opened to the public for the first time today, is the last surviving structure of an armament depot constructed by the British within the huge Naval Base in the Talbot’s Hill and Attap Valley area. A ammunition and armament storage magazine, specifically Magazine No. 4, it was one of seven other bomb-proof magazines that were built into Talbot’s Hill by the British before 1942.
The National Heritage Board (NHB), which has been studying the site since April 2014, has also established with the help of a 1945 map of the Naval Base, that the magazines were part of a network of eighteen bunkers, warehouses and workshops spread over the Attap Valley site, that formed the Royal Naval Armament Depot.
Evidence points to the magazine, which is the size of two 5-room HDB flats, being used by the Japanese during the occupation – a cache of Japanese weapons and ammunition was found by MINDEF when they used the site for the Sembawang Ammunition Depot.
According to NHB, part of the floor of the bunker, now a mess of mud and water, would have had rail tracks running over them to allow the ammunition to be moved in and out, accounting for the rusty colour of the mud and water in the bunker. While there is nothing left of the tracks to be found, there are several fixtures and fittings that might have originally been there at the time of its completion. This includes vents from an all important ventilation system, light fixtures, and pipes. A travelling gantry hoist, complete with a sign giving its Safe Working Load rating, can be seen in the inner chamber where the ammunition would have been stored. Access into the inner chamber is via a curved passageway designed so as explosions could be contained.
Talbot’s Hill and the surviving magazine under it now lies well within a fenced up area of land, which was returned to the State by MINDEF when the depot was decommissioned in 2002. Access to it is only via the NHB tours, being organised as part of a Battle of Singapore commemoration that coincides with the 73 anniversary of the Fall of Singapore and also the 70 anniversary of the liberation in September 1945. More information on this, including the Case Files from the Singapore War Crimes Tribunal Exhibition scheduled to open next week at the National Museum of Singapore, can be found at the NHB website.
