Johore Battery


Johore Battery is one of the heritage trails in Singapore having a history that dates to 1930s. Johore Battery site comprises 3 guns, part of 29 coastal guns, that were installed in Singapore. The three weapons are among the largest ever coastal guns in the country. In mid 1930, these coastal guns at Changi once defended the naval base that was located at Sembawang.

History of Johore Battery
Three guns exclusively installed at Changi were called Johore Battery. Two others were set up in Buona Vista. The Changi guns were named so as the Sultan of Johore, Ibrahim II, OF Malaysia donated 500,000 pounds for silver jubilee celebration to th King of United Kingdom, George V. Around 400,000 pounds was used to get the guns installed at Changi and was named after the Johore.

It became an important defense mechanism for Singapore coasts. The Johore Battery site had a number of tunnels built to store ammunitions.

These guns could fire all 15-inch shells. In world history, these guns are largest ever installed anywhere outside Britain post World War II. They were tested first in Britain in 1934 and 7 of them defended the coastline there before being shipped to Singapore. The British army had sealed the site until rediscovered in 1991. Replicas of the guns and shells are still seen there.
