World War II concrete pillboxes, built along Singapore's eastern and southern coast, were part of the British beach defences. Positioned at about 550-metre intervals, these pillboxes complemented gun emplacements at the forts, searchlight batteries, anti-tank and anti-boat defences, mines and barbed wire along the coastline. The pillboxes were mounted with machine-guns manned by machine-gunners to repel attacks from the sea and the surrounding terrain.
This machine-gun pillbox lay within the World War II defence sector of the 1st Malaya brigade. It was likely used by the Malay Regiment in the fierce defence of the Pasir Panjang Ridge against the onslaught of the advancing troops of the Japanese 18th Division.
