It was sounded to warn local people when enemy aircraft were approaching.
Portsmouth suffered many air raids during the war largely due to enemy attempts to target the Dockyard. As a result large parts of the city were devastated.
The siren was kept in place into the 1980s, as part of a nationwide nuclear attack warning system.
There were also smaller types of mobile air raid sirens which were used indoors in factories.
