In the 1970s when I was Resident Surgeon at the General Hospital, Batticaloa I heard the following story. Inside the old Dutch fort connecting the rampart with the commanders quarters there was a metal - wooden floored bridge.
A night watcher inside the fort had heard someone walking on the wooden floor in the dead of the night. He had gone to investigate. He had seen a man dressed in metal armor and wearing a metal cap walking to and fro on this bridge. The metal ramp is now converted as a concrete bridge. I took this picture recently.
