The Up Helly A' is a festival celebrated on the 24th day after Christmas in Shetland. The celebrations involve a parade of 1000 guizers led by a Jarl, and culminates in the burning of a galley (an elaborate replica of a Viking ship). The Up Helly A exhibition is open year round, and features the Viking-themed costumes used in the history of the festival, as well as a galley, the public proclamations published before the festival each year, and paintings of the festivities.
