The Outer Hebrides is a chain of more than 100 islands and small skerries located about 70 kilometres (43 mi) west of mainland Scotland.
To the south across the Sound of Harris lie the Uists and Benbecula, which were joined by a series of causeways constructed between 1940 and 1960 to improve transport links.
[9] The definition of an island used in this list is that it is "land that is surrounded by seawater on a daily basis, but not necessarily at all stages of the tide, excluding human devices such as bridges and causeways".
Ensay, Kisimul Castle and Eilean na Cille are "included in the NRS statistical geography for inhabited islands but had no usual residents at the time of either the 2001 or 2011 censuses".
On 4 May 1746, Bonnie Prince Charlie hid on Eilean Liubhaird with some of his men for four days whilst Royal Navy vessels patrolled the Minch.
For example, Haswell-Smith (2004) treats Eileanan Iasgaich[Note 11] as a single island of 50 ha, although during high tides it becomes several tidal islets—none of which is ever connected to the "mainland" of South Uist.
The islet on which Kisimul Castle stands is the ancient seat of Clan MacNeil and Shillay in the Monach Isles had a staffed lighthouse until 1942.
[28] The tiny Beasts of Holm of the east coast of Lewis were the site of the sinking of the Iolaire during the first few hours of 1919,[29] one of the worst maritime disasters in United Kingdom waters during the 20th century.
Calvay in the Sound of Barra provided the inspiration for Compton MacKenzie's 1947 novel Whiskey Galore after the SS Politician ran aground there with a cargo of whisky.
