Photos shared by friends, Thanks for attending this event! πΈπ Hike to Fort Serapong β Hidden WWII Ruins & Highest Point of Sentosa. Revisited the former Serapong Chapel, likely the largest abandoned hall in the area. The small side room in the corner is believed to have been used by the priest to change robes before service.
At the summit, we explored the largest Blue Bunker, sitting at what is likely the highest point of Sentosa (~90m above sea level). Another bunker, now engulfed by a massive banyan tree, has become a unique and photogenic hidden spot.
We took a relaxing break with snacks at Cement Hill, enjoying beautiful sea views and clear skies. Along the way, we met two other groups exploring the area, a few friends ventured deeper into the tunnels and ruins of Fort Serapong.
We also traced an interesting route from the Serapong Underground Reservoir to the Blue Hut (likely an old water pump room), following a network of historic pipes β a reminder of the fortβs hidden infrastructure.
When heavy rain rolled in, we cut short the exploration and head over to nearby Fort Connaught.
Key highlights at Fort Connaught:
- Battery Observation Tower
- Underground Ammunition Magazine
- Remains of the #3 Main Gun foundation
These historic forts were part of the British coastal defence network protecting Keppel Harbour from the 1880s through World War II β a hidden chapter of Singaporeβs military history now reclaimed by nature.
