Lé Viaer Marchi (Guernésiais: the old market) is an annual festival held in Guernsey on the first Monday of July.
Held since 1969, Lé Viaer Marchi is an evening show, organised by the National Trust of Guernsey. It showcases local craftsmanship in Guernsey's history and holds displays showing the way in which Guernseymen and women used to live. Delicacies are served, with Guernsey Bean Jar being one of the most popular. Guernsey Gâche (a type of fruit bread) and cider are also on offer. There are also a selection of activities for children to make the evening accessible to all islanders. There are stalls set up for various bric-a-brac. Local woodcarvers showcase their wares, and local women make Guernsey butter and lace. Entertainment includes traditional dancing, bands performing local folk music, street entertainers, and sometimes Punch and Judy shows.
