The mystery of Bukit Gombak

13 03 2014

An area of Singapore that does seem to have an air of mystery about it is Bukit Gombak. The location of what reputedly was one of Singapore’s most haunted places, Hillview Mansion, which once stood high on its eastward facing slope, the hill and its environs has also gained a somewhat sinister reputation for other ghostly encounters, some of which seem to have been attributed as the cause of several unfortunate incidents that have taken place in the hill’s disused water filled quarries.

The rainwater filled former Gammon Quarry, now part of a park known as Little Guilin, is one that seems to hide much in terms of mystery.

Besides the supernatural, a mystery that is of a less sinister nature is that of a concrete structure. Now in a state of collapse, the structure stands at the top of a steep incline that runs up from a cut leading to the former Seng Chew Granite Quarry. The structure is one that was documented by my friends from the One° North Explorers, who had first stumbled upon it sometime in 2005 when it was in better shape and was being used to house a makeshift shrine (see: The Forsaken Quarry of the West And the Mysterious Shrine).

Little Guilin is an area of much beauty that some suspect hides several secrets.

It was in the company of James Tann, a long time resident of the area, and Andrew Him and Chris Lee of One° North Explorers, that I was to  pay a visit to the structure over the weekend, with the intention to search for further clues as to what it may have been.  From James, we were to learn quite a fair bit that wasn’t just confined to the area’s history, but also to the area’s geology. It was from the depths of his vast local knowledge that I was to discover that the rocky ground on which I had been standing on was in fact one of the oldest rock formations that I could stand on in Singapore (see: Singapore Landscapes: the secret lake).

With the area being one that had a strong connection with the military – the British having maintained a military installation and radar station on the ridge line that ran from Bukit Gombak to Bukit Panjang, and the Japanese having set up camp on the hill during the occupation, James had suspected that the collapsed structure might have been a Japanese built pillbox from World War II. There was also a suggestion from the One° North Explorers that it could have been a blasting shelter, as one might have expected to find on the grounds of the quarry.

Standing on its foundation of Gombak norite and in its collapsed state, there wasn’t much more that the structure did give away. What did seem like its flat roof, had completely caved in, burying whatever clues that might otherwise have been discovered under it. The only remnant of the structure that seemed to be left standing was a wall of concrete bricks with little else but a semi-corroded steel backing plate that might have been used to act as a support for a mounting inside the structure.

Built into the contours of the slope on the side of the quarry, there was also evidence of what did seem to be a substantial concrete structure. That might possibly been erected to act as a blast barrier – supporting the suggestion that what was there may have been that blasting shelter, along with the fact that the collapsed structure had its entrance on the slope away from the quarry. Kim Frost, a WWII vehicle expert,  did also unearth a grove on the top of the thick layer of concrete that does resemble a drain – possibly to provide drainage from runoff flowing down the slope.

While all does seem to point to the structure being a blasting shelter, that is still this lingering suspicion that the structure could still be a military one, including it being an entrance to a tunnel – similar to what we do see of the tunnels at Marsiling that was recently in the news, especially so when a newspaper report I came across does give evidence of their construction at Bukit Gombak.

The report, in the 17 November 1953 edition of The Straits Times that was headlined “$50 MIL. OIL PIPE PLAN IS ABANDONED“, relates to the abandonment of  what it called a “top-secret project”, that is spite of half the budgeted sum already expanded in the twelve years of effort, interrupted by the war, put into carving out tunnels and oil storage tanks under Bukit Gombak. That was all part of an attempt to build what would have been a hidden storage facility, capable of holding “hundreds of thousands of gallons of petrol [sic]” to fuel the Far East Fleet based at the Naval Base.

The project would have seen some fourteen underground oil tanks built along with access and maintenance tunnels and a pumping station, and with a network of pipelines laid. From the report, we can surmise that work would have started in 1941 with the Japanese continuing with it during the occupation. The Royal Navy recommenced work on it in 1946 before abandoning the project in 1953. The report does mention that the tunnels and tanks were filled up after the project was stopped as well as “several miles of underground pipes” dug up.

This certainly is an interesting parallel to set of tunnels that have been found at Marsiling that was the subject of a recent WWII related tour organised by the National Heritage Board. While that, located on what was fringe of the Naval Base, is thought to have been built as an aviation fuel storage facility, the one at Bukit Gombak located away from the Naval Base, was being built to serve as a fuel storage for the naval fleet.

With the military presence continuing at Bukit Gombak and the developments that have taken place around the hill, there is little more evidence that can be found of what the structure might once have been. It may also not be long before the structure disappears completely – survey markers seen in the area do show signs there is recent interest in perhaps the redevelopment of the area, which does mean that we may never unravel the mystery of what the collapsed structure was.

Developments in the area mean little else is left that can be found.

Hi Jerome, where is the location of this collapsed structure? I know where is Seng Chew quarry and have climbed up the cliff on the left of the lake, walked past the vegetation till Mindef fence and along the fence to Hillview mansion. But have not seen this structure before.

If you walked up the left cliff , most likely you walked on top of the “blast shelter” and didn’t notice. My guess the structure was left of thre blast shelter. Really the nature took over a lot of this area.

I was stationed here (in the RAF) from 1965 – 67 and it was a surveillance radar station. It was also part of the radio relay chain linking RAF stations around the Island. Some of the concrete may have been from the radar “ops” building that was partially underground. The (horn) aerials for the radio relay were mounted on a steel mast.
During “Confrontation” (with Indonesia) we had a single barrel Oerlikon mounted outside the relay building (no ammo that I remember) which we might shoot at any attacking aircraft!

As a boy lived in a bungalow at Bukit Gombak (1946 – 1948/49) with my Mother, Father and older sister
Father was a civil engineer working for the Admiralty at the Naval Base on war damage repairs.
From memory the area was very rural and I recall going for family evening walks and collecting spent bullet cases
I also seem to remember that to get to the bungalow we would turn off the Bukit Timah Road and climb steeply via a level crossing manned Malaysian police wearing Royal Navy ratings uniform.
There was a large open topped reinforced concrete tank in the bungalow grounds which used to collect rainwater and in which I learnt to swim, it was thought that the tank was built by the Japanese as part of an anti malaria programme.
