Up Helly Aa

Up Helly Aa is a type of fire festival held annually from January to March in various communities in Shetland, Scotland, to mark the end of the Yule season. Each festival involves a torchlit procession by squads of costumed participants that culminates in the burning of an imitation Viking galley. The largest festival held in Lerwick, Shetland's capital, involves a procession of up to a thousand guizers who march through the streets of Lerwick on the last Tuesday in January. The other rural festivals see lower numbers of participants in accordance with their lower populations.
