Fort Siloso was then converted into a military museum in 1974, displaying its history and various naval guns. Other coastal guns (both British and Japanese) from different parts of Singapore, such as a pair of Japanese naval cannons discovered and brought over from Mandai, were put here for display. It had previously held the display of the British surrender of Singapore in February of 1942 until its relocation to the former Ford Motor Factory (the actual site of the British surrender) in Bukit Timah in the early 2000s.
