Shetland's Fire Festival Season lasts from January until March. Here are some highlights from the biggest event in the calendar, Lerwick Up Helly Aa, which took place on the last Tuesday in January and lasted a full 24 hours.
The morning
The morning of Lerwick Up Helly Aa sees the Jarl Squad (Vikings), led by the Guizer Jarl (Viking chief) proudly parade through the streets of Lerwick. It's an opportunity for the squad to show off their magnificent Viking costumes, which take years of planning to create, and to pose for photos next to the galley (Viking longship), which will be ceremoniously burned later in the evening. Joining the Senior Lerwick Up Helly Aa Jarl Squad, are the Junior Jarl Squad, involving pupils from Lerwick's secondary school.
