Every year, at the fag end of January (this year it's on January 31), the small town of Lerwick in Shetland, Scotland, celebrates the fieryUp Helly Aa day. On this day actors, called guisers, mark the end of the Yule season, with a fire procession and a ceremonial burning of a Viking galley. Although smaller versions of this festival is held across rural Scotland, Shetland's celebration is the biggest. The festival started in 1881, replacing the outlawed celebration of 'tar barrelling' where young men would drag barrells of burning tar on sledges and set fire to all sorts of things. Up Helly Aa isa more sedate and law abiding festival. The processions and festivities begin in the morning when the chief gruiser, called Gruiser Jarl, dressed in Viking finery, leads his similarly attired Jarl Squad through the streets, stopping offat various location and even signing a 'Bill' of jokes and satire. In the evening, more processions are held, this time with the squad carrying burning torches. Right at the end, the torches are tossed into a Viking ship replica and burned to the ground. Other villages and towns continue to host their own Up Helly Aa all the way till March 17. For more information, look up shetland.org.
