There’s A Secret Abandoned WW2 Bunker In Woodlands Even Residents Don’t Know Exists

Attap Valley Bunker in Woodlands

---

With new shopping malls and MRT stations popping up on empty lands ever so often, it’s hard to imagine that abandoned spaces in Singapore still exist. Yet, there are several such WW2 landmarks scattered around the island. So, when this Eastie heard about Woodlands’ hidden Attap Valley Bunker, I thought, “If it’s in the West, I’ll probably never visit IRL.”

As it turns out, even if you don’t mind the trek in the jungle, this remnant from our days as a British colony is currently off-limits to the public. Then what’s the point of writing about it you ask? Well, you can get right to the bunker’s entrance, albeit only on Google Maps. Plus, it doesn’t hurt to know a little more about our history.

Attap Valley Bunker was originally known as Magazine No. 4

Back in 2015, the National Heritage Board held Attap Valley Bunker tours of some never-before-seen pre-war and wartime sites. This was to commemorate the 73rd anniversary of the battle for Singapore and the 70th anniversary of our country’s subsequent liberation.

It’s giving “doorway to another world” vibes.

The Attap Valley Bunker was one of the stops during the tour, and only a select few were led inside this British-made pre-war military installation. Before it gained its much more ominous, cooler-sounding name, it was simply referred to as Magazine No. 4.

So, what was it used for exactly? The bunker was part of a network of 18 bomb-proof underground bunkers across Singapore.

These bunkers were originally an integral part of their “Singapore strategy” to protect themselves against the Japanese invasion and served as storage facilities for the British Singapore Naval Base. If you’re wondering how successful this strategy panned out to be, you should have paid more attention in History class. Spoiler alert: it wasn’t successful.

Attap Valley Bunker lies hidden at the bottom of a hill – formerly known as Talbots Hill – where there used to be 6 more similar storage facilities. Unfortunately, only this bunker still stands today.

After trudging through a corridor of ankle-deep murky water, the tour group reached the 300sqm storage area. They found 2 cranes with manufacturing labels dating back all the way to 1937.

Researchers have found that these underground bunkers were most likely used to assemble explosives and detonators to be sent to battleships before WW2. Once the Japanese occupation went underway, their army took over the bunkers to store their own ammunition.

11 groups in total had the rare opportunity to venture into the bunker back in 2015. As of now, there are no known plans to redevelop the area or open it to the public, and it remains a restricted space. So, don’t expect to see any paranormal investigators prowling around these parts anytime soon.
