Church bells in Guernsey's capital, St Peter Port will ring for eight hours in tribute to those who died during World War One.
The St Peter Port Parish church bells will ring every 20 seconds for the 1,470 believed to have died from the Bailiwick.
The event will take place on Monday 4 August, 100 years since the declaration of war against Germany.
Relatives of those who died have been invited to ring a bell on the day.
Organisers say bells are usually rung on a special, joyful occasion like the anniversary of liberation from German occupation.
A spokesman said: "The idea of linking the chiming with the number of those lost, in the form of a protracted knell, seems appropriate."
The bells will be rung throughout the day until about 17:10 BST and organisers hope this will be "noticed by everyone who passes through the town centre".
