In the late 1930s, during the height of World War II, the British built a chain of tunnels and underground battlements along the southeast coast of Singapore at the anticipation of a sea-borne attack by the Japanese. Within the tunnels, they placed a series of three long guns designed to reach ships assailing the island from the bay. The passageways were also used to store the massive 15-inch ammunition shells fired from the guns. After the war, the battlement was abandoned, the tunnels sealed, and Johore Battery remained Singapore’s best-kept secret until 1991, when it was discovered while the Prisons Department was clearing the area.
Today, visitors who attend Johore Battery, located in the Changi district of Singapore, can view replicas of the mammoth guns and explore the maze of covert tunnels of that snake underneath the fort. One of the coolest things to do at Johore Battery is to try lifting the replica ammunition shell, which weighs 800kg!
Entrance to Johore Battery is free, and the park is open from 9-5 everyday. It is located on Cosford Rd., just off of Upper Changi Rd. North. To get there, take the MRT to Tanah Merah Station and, from there, hop on SBS Transit Bus 2 to Selarang Camp.
Johore Battery makes a nice morning sightseeing activity and is a relaxing way to learn more about Singapore’s sorted war history. It shouldn’t take more than about an hour to fully explore the Battery.
