Fort Siloso, Sentosa: History, highlights and visitor guide

History and context

The story behind Fort Siloso

The fort was built by the British in the 1870s and 1880s to guard the western approach to Keppel Harbour; sources differ on whether the date was 1874 or 1878. It was manned by the Royal Artillery and the Singapore Artillery Corps. In February 1942 its guns were turned inland against the Japanese advance, and during the occupation it served as a small prisoner-of-war camp.

After the war it passed to the Royal Navy and Gurkha units, then to the Singapore Armed Forces after 1967. It became a military museum in 1974 and a national monument in 2022.

Why it matters

Why Fort Siloso is worth your time

Forts like this explain why Singapore was fortified, and why Sentosa was known as Pulau Blakang Mati before it became a resort. Fort Siloso is the only surviving coastal gun battery of the twelve that made up Fortress Singapore, which gives it a rarity few other sights on the island can match.

It was gazetted a national monument on 15 February 2022, Singapore's 74th. For travellers who see Sentosa as only rides and beaches, a couple of hours here adds the island's wartime background, and it can be a calmer half-day plan for grandparents.

How to experience it

Start at the Surrender Chambers at the entrance, which show how the British and Japanese surrenders were staged and include interactive wartime footage. Then follow the trail uphill to the gun platforms, where the barrels still point out over Keppel Harbour, and walk through the tunnel complex and command post.

The history matters here. The guns were built to face the sea from the south, but when the Japanese advanced from the north in February 1942, they were turned around to fire inland. During the occupation of 1942–45, the fort served as a small prisoner-of-war camp. Reading a few of the panels first will make the walk more meaningful.

Fort Siloso is on the western end of Sentosa, so combine it with the Siloso Beach area or the cable car's Siloso Point station rather than making a separate trip.
