Stage for civil defense siren

                                               Stage for civil defense siren is situated in front of Jaffna St. John College. A civil defense siren is used to provide emergency warning to public of approaching danger of aircraft attack during the Second World War II period. When Singapore fell to the Japanese in February 1942, Sri Lanka became a central base for British operations in Southeast Asia, and Trincomalee Harbor was an indispensable strategic bastion for the British Royal Navy, it was an irresistible military target for the Japanese. Hence Trincomalee harbor area was targeted by aircraft attacks. During the period British Colonial Government had established this kind of emergency warning center in the country. This siren was acted as alarming center to alert the Jaffna East area.
