Muckle Flugga lighthouse was designed and built by the brothers Thomas and David Stevenson in 1854, originally to protect ships during the Crimean War. First lit on 1 January 1858, it stands 20 m high, has 103 steps to the top, and is Britain's most northerly lighthouse. In March 1995 it was fully automated.
In 1851 it was decided to build a lighthouse on north Unst but, because of difficulties in determining the exact location, nothing had been done by the start of 1854. During the Crimean War, the government urged the commissioners to set up a light on Muckle Flugga to protect Her Majesty's ships. A temporary lighthouse 15 m high was built 61 m above sea level and lit on 11 October 1854. It was thought to be high and safe enough to withstand the elements, but when winter storms began waves broke heavily on the tower and burst open the door to the living quarters. The principal keeper reported that 12 m of stone dyke had been broken down, and the keepers had no dry place to sit or sleep. Plans were made for a higher and more permanent lighthouse, but there were still disagreements about where to locate it, Muckle Flugga or Lamba Ness. The orders to start the work on the new Muckle Flugga tower were finally given in June 1855. The lighthouse's original name was 'North Unst', but in 1964 that was changed to 'Muckle Flugga'.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
