Shetland's spectacular annual Up Helly Aa festival came to a fiery conclusion in Lerwick last night. The event celebrates the Shetland Islands' Viking heritage, and is traditionally held on the last Tuesday of January.

Up Helly Aa concludes with the spectacular burning of a replica Viking longboat.

During the day, a band of latter-day Viking warriors known as the Jarl Squad attend a series of marches and public appearances, including a school where they teach children about Vikings.

The event attracts visitors from across the world and is seen as a tourism boost to the Shetland Islands.
