The Up-Helly-Aa (“The end of the holly days”) festival takes place at Shetland Islands.
It is one of the glories fire festivals in the world. All the participants are dressed as Vikings (or other customs that are changed yearly). With the torches that they carry they set on fire a huge Viking ship as a sacrifice to the god of the sun.
After the ecstasy of the fire the next day is a vacation day.
