1. Changi Commando Barracks (cum Changi Prison)
Barracks for around 15, 400 British and Australian Troops during WWII. POWs were kept there too.
2. Dairy Farm House
History of this place is somehow unknown. There are empty bottles hanging on sticks and plants.Maybe you might want to explore the place yourself. Located at Dairy Farm Road, leading to BKE.
3. Old Ford Motor Factory
History was made there on 15th Feb 1942 when the Head of the Allied forces, Lt General A. E. Percival, surrendered to general Yamashita of the Japanese Forces. It’s also said that most patriotic Japanese soldiers and high rank officers ‘martyred’ themselves upon receiving news that Japan was losing the war, but I only read that it’s a legend.
