    Overview

    St Kilda (Scottish Gaelic: Hiort) is a remote archipelago situated 35 nautical miles (65 kilometres) west-northwest of North Uist in the North Atlantic Ocean. It contains the westernmost islands of the Outer Hebrides of Scotland. The largest island is Hirta, whose sea cliffs are the highest in the United Kingdom; three other islands (Dùn, Soay and Boreray) were also used for grazing and seabird hunting. The islands are administratively a part of the Comhairle nan Eilean Siar local authority area. The origin of the name St Kilda is a matter of conjecture. The islands' human heritage includes unique architectural features from the historic and prehistoric periods, although the earliest written records of island life date from the Late Middle Ages. The medieval village on Hirta was rebuilt in the 19th century, but illnesses brought by increased external contacts through tourism, and the upheaval of the First World War, contributed to the island's evacuation. Permanent habitation on the islands possibly extends back two millennia, the population probably never exceeding 180; its peak was in the late 17th century. The population waxed and waned, eventually dropping to 36 in 1930, when the remaining population was evacuated. Currently, the only year-round residents are military personnel; a variety of conservation workers, volunteers and scientists spend time there in the summer months. The entire archipelago is owned by the National Trust for Scotland. A cleit is a stone storage hut or bothy unique to St Kilda; there are known to be 1,260 cleitean on Hirta and a further 170 on the other group islands. Two different early sheep types have survived on these remote islands: the Soay, a Neolithic type, and the Boreray, an Iron Age type. The islands are a breeding ground for many important seabird species including northern gannets, Atlantic puffins, and northern fulmars. The St Kilda wren and St Kilda field mouse are endemic subspecies. It became one of Scotland's seven World Heritage Sites in 1986, and is one of the few in the world to hold joint status for both its natural and cultural qualities.

      Soay (Scottish Gaelic: Soaigh) is an uninhabited islet in the St Kilda archipelago, Scotland. The name is from Old Norse Sauðey, meaning "island of sheep".
