One of a pair of cannons that was meant to shoot 9-pound cannon balls. Playing a decorative role rather than a defensive one, the cannon was fired three times a day at 5am, 1pm, and 9pm to announce the hour. It was also fired as a salute and warning of town fires. Next to the cannon is South Battery, the site at which the main battery of guns was mounted to defend Singapore in the 19th century.
