Imperial War Museum North, The Quays, Sat to 31 Jan, iwm.org.uk Iain Aitch Up Hell Aa, Lerwick Britain's most northerly town might not seem the most appealing destination in deepest January, but for 16 hours a year, Lerwick plays host to some of Europe's "hottest" nightlife. Between dusk and dawn, nearly 1,000 "guizers" in full Viking garb storm the streets with blazing torches and rolling tar barrels, set light to a giant galley, and proceed to dance − and drink − the night away at a mass ceilidh concentrated across 11 local halls. The tradition began in the 1880s, and is now our continent's biggest fire festival, attracting up to 5,000 spectators. Who said winter was for staying indoors?
