People in Jersey will gather outside Gorey Castle on Saturday morning to participate in the biggest outdoor piece of artwork Jersey has ever seen.
The flag is inspired by the medieval practice of landscape drawing
A giant flag is being created to form a dramatic backdrop for the site of the Jersey Revels at the end of June.
Visitors to the castle will be greeted by the sight of a magnificent 50m flag hammered to the hillside.
Jersey Revels, which take place between 25-27 June, marks 800 years of the island's links with the Crown.
Local artist Ian Rolls says he was inspired by the ancient medieval practice of drawing on the landscape.
Six design tables have been set up and organisers hope to have more than 3,000 small flags planted in the shape of a medieval heraldic flag.
The giant artwork will also be seen by Prince Charles when he visits the island later this month.
