Participants dressed as Vikings march past during the annual Up Helly Aa festival in Lerwick, Shetland Islands. Up Helly Aa celebrates the influence of the Scandinavian Vikings in the Shetland Islands and culminates with up to 1,000 'guizers' (men in costume) throwing flaming torches into their Viking longboat and setting it alight later in the evening.
