These have been around since ww2 days and are still seen today even if u dont notice any !!!
Often they will be on top of a tall building in most towns and cities sometimes they are just mounted on a post
They were decommissioned in 1993 but some still remain in place and some are still in use
A small number of remaining sirens (around 1,200) are kept exclusively for localized risks like severe flooding, gas or nuclear power plants, chemical plants, or military/dockyard bases,
