Sentosa - Fort Siloso
Fort Siloso holds a large collection memorabilia, original guns and cannons of World War II. It is opened 10am - 6pm daily with the last entry at 5.30pm. That's good as I'm pretty sure the old WWII tunnels will feel a little creepy at nightfall. It can get a quite hot up there in the humid Singapore weather so be prepared to work up a sweat wandering around the place.
