The Shetland Islands are Great Britain’s most northerly islands, situated nearly fifty miles northeast of the Orkneys. Lerwick is the capital of the principal island of Mainland and is Britain’s most northerly town. Founded on the fishing industry and with strong Viking connections, little now remains of the old village of Lerwick. Features of interest include the Cromwellian Fort Charlotte and annual Norse fire festival, Up-Helly-Aa, held every January. On the southern tip of the island is Jarlshof, site of ruins of several Stone Age and Bronze Age dwellings as well as wheel-houses from the Iron Age. Elsewhere on the island is Clichimin Broch, another prehistoric site containing a Bronze Age fort.
