Buy the Singapore Bunker Museum online to visit the underground command center and learn about Singapore's history in World War II. A professional guide will explain each exhibition to take you back to this historic place. A very interesting trip, the tour guide was very good, explained a lot of knowledge about Singapore during World War II, and could combine the real scene and film to have a more intuitive feeling. But the whole process is explained in English, and the children who are too small (under 8 years old) are not very easy to understand.
