Traditionally, St Peter's eve was a time for lighting bonfires and fireworks, and fireworks still form part of the present-day event. During Mevagissey Feast there are also parades, demonstrations and a celebration of the heritage and history of the community. One of the highlights of the event is the carnival, when local residents dress in costumes and process through the village.
Mevagissey Feast is held near 29th June every year. Like many Cornish fishing communities Mevagissey's patron saint is St Peter, who was actually a fisherman himself.
