From at least the early years of the 19th century a gun was
fired from Castle Cornet at noon and another at 21.30 to recall soldiers of
the garrison to their barracks – the Curfew gun. Originally the gun was
fired from the Cavalier Battery on the citadel. A 9-pounder gun was used,
but this was later replaced by an 18-pounder. The gun was discontinued in
1923 as an economy measure.
The Noonday Gun ceremony in Castle Cornet was re-introduced as a visitor
attraction in 1974. The gun is “fired” using a saluting charge of
approximately 25 grammes. The charge is placed twelve to eighteen inches
down the barrel of the gun and detonated electrically.The gun is also used on ceremonial occasions, for example to mark the beginning and end of the 2-minute silence on Armistice Day.
The gun is mounted on the only remaining original wooden garrison carriage in the castle. Its design is similar to that used on warships, but it has iron rather than wooden trucks (wheels).
Both gun and carriage stood for many years on the Parade Ground at Les Beaucamps Arsenal. They were transferred to Castle Cornet in 1953.
(The Blomefield Pattern gun was supposed to be a lighter replacement for the Armstrong for sea service, but in the event it wasn’t. Its cascable is simplified and lightened – a single curve centred on mid-chamber. A cast-in loop is designed to hold a breech rope. The Blomefield was standard issue on Naval ships by 1794, but Armstrongs were still on ships in 1808. Numbers of the guns were also made available for garrison use. Two 32-pounders were located in Castle Cornet in 1826. Nine were in the Castle in 1870, although smooth bores were by then obsolete.)
