The Isle of Arran (; Eilean Arainn) or simply Arran is an island off the west coast of Scotland. It is the largest island in the Firth of Clyde and the seventh-largest Scottish island, at 432 km2. Historically part of Buteshire, it is in the unitary council area of North Ayrshire. In the 2022 census it had a resident population of 4,618. Though culturally and physically similar to the Hebrides, it is separated from them by the Kintyre peninsula. Often referred to as "Scotland in Miniature", the island is divided into highland and lowland areas by the Highland Boundary Fault and has been described as a "geologist's paradise".

Arran has been continuously inhabited since the early Neolithic period. Numerous prehistoric remains have been found. From the 6th century onwards, Goidelic-speaking peoples from Ireland colonised it and it became a centre of religious activity. In the troubled Viking Age, Arran became the property of the Norwegian crown, until formally absorbed by the kingdom of Scotland in the 13th century. The 19th-century "clearances" led to significant depopulation and the end of the Gaelic language and way of life. The economy and population have recovered in recent years, the main industry being tourism. However, the increase in tourism and people buying holiday homes on the island, the second highest rate of such homes in the UK, has led to a shortage of affordable homes on the island. There is a diversity of wildlife, including three species of tree endemic to the area.

The island includes miles of coastal pathways, numerous hills and mountains, forested areas, rivers, small lochs and beaches. Its main beaches are at Brodick, Whiting Bay, Kildonan, Sannox and Blackwaterfoot.

Etymology

Most of the islands of Scotland have been occupied consecutively by speakers of at least four languages since the Iron Age. Therefore, the names of many islands have more than one possible origin, including Arran. Mac an Tàilleir (2003) says the name "is said to be unrelated" to those of Arranmore or the Aran Islands in Ireland, which come from Irish Árainn meaning "kidney-shaped", though he does not rule out this derivation.

Unusually for a Scottish island, Haswell-Smith (2004) and William Cook Mackenzie (1931) offer a Brythonic derivation and a meaning of "high place" (compare Middle Welsh aran) which at least corresponds with the geography – Arran is significantly loftier than all the land that immediately surrounds it along the shores of the Firth of Clyde.

Any other Brythonic place-names that may have existed, save perhaps for Mayish, were later replaced on Arran as the Goidelic-speaking Gaels spread from Ireland, via their adjacent kingdom of Dál Riata.

During the Viking Age it became, along with most Scottish islands, the property of the Norwegian crown, at which time it may have been known as Herrey or Hersey. As a result of Norse influence, many current place-names on Arran are of Viking origin.

History

Prehistory

Arran has a particular concentration of early Neolithic Clyde Cairns, a form of Gallery grave. The typical style of these is a rectangular or trapezoidal stone and earth mound that encloses a chamber lined with larger stone slabs. Pottery and bone fragments found inside them suggest they were used for interment and some have forecourts, which may have been an area for public display or ritual. There are two good examples in Monamore Glen west of the village of Lamlash, and similar structures called the Giants' Graves above Whiting Bay. There are numerous standing stones dating from prehistoric times, including six stone circles on Machrie Moor (Gaelic: Am Machaire).

Pitchstone deposits on the island were used locally to make various items in the Mesolithic era. In the Neolithic and the Early Bronze Age pitchstone from the Isle of Arran or items made from it were transported around Britain. It is thought to be the source of most, it not all, pitchstone artefacts found in the United Kingdom. There are more than 100 document sources of the material on the island that prehistoric people could have collected/mined from.

Several Bronze Age sites have been excavated, including Ossian's Mound near Clachaig and a cairn near Blackwaterfoot that produced a bronze dagger and a gold fillet. Torr a' Chaisteal Dun in the south west near Sliddery is the ruin of an Iron Age fortified structure dating from about AD 200. The original walls would have been 3 m or more thick and enclosed a circular area about 14 m in diameter.

In 2019, a Lidar survey revealed 1,000 ancient sites in Arran including a cursus near Drumadoon. Excavation began in 2023. This is believed to be the only complete example in Britain.

Gaels, Vikings and Middle Ages

An ancient Irish poem called Agalllamh na Senorach, first recorded in the 13th century, describes the attractions of the island.

The monastery of Aileach founded by St. Brendan in the 6th century may have been on Arran, with Holy Isle being a centre of Brendan's activities. The caves below Keil Point (Gaelic: Rubha na Cille) contain a slab which may have been an ancient altar. This stone has two petrosomatoglyphs on it, the prints of two right feet, said to be of Saint Columba.

In the 11th century Arran became part of the Sodor (Old Norse: 'Suðr-eyjar'), or South Isles of the Kingdom of Mann and the Isles, but on the death of Godred Crovan in 1095 all the isles came under the direct rule of Magnus III of Norway. Lagman (1103–1104) restored local rule. After the death of Somerled in 1164, Arran and Bute were ruled by his son Angus. In 1237, the Scottish isles broke away completely from the Isle of Man and became an independent kingdom. After the indecisive Battle of Largs between the kingdoms of Norway and Scotland in 1263, Haakon Haakonsson, King of Norway reclaimed Norwegian lordship over the "provinces" of the west. Arriving at Mull, he rewarded a number of his Norse-Gaelic vassals with grants of lands. Bute was given to Ruadhri and Arran to Murchad MacSween. Following Haakon's death later that year Norway ceded the islands of western Scotland to the Scottish crown in 1266 by the Treaty of Perth. A substantial Viking grave has been discovered near King's Cross south of Lamlash, containing whalebone, iron rivets and nails, fragments of bronze and a 9th-century bronze coin, and another grave of similar date nearby yielded a sword and shield. Arran was part of the medieval Bishopric of Sodor and Man.

On the opposite side of the island near Blackwaterfoot is the King's Cave where Robert the Bruce is said to have taken shelter in the 14th century. Bruce returned to the island in 1326, having earlier granted lands to Fergus MacLouis for assistance rendered during his time of concealment there. Brodick Castle played a prominent part in the island's medieval history. Probably dating from the 13th century, it was captured by English forces during the Wars of Independence before being taken back by Scottish troops in 1307. It was badly damaged by action from English ships in 1406 and sustained an attack by John of Islay, the Lord of the Isles in 1455. Originally a seat of the Clan Stewart of Menteith it passed to the Boyd family in the 15th century. For a short time during the reign of King James V in the 16th century, the Isle of Arran was under the regency of Robert Maxwell, 5th Lord Maxwell.

Modern era

At the commencement of the Early modern period James, 2nd Lord Hamilton became a privy counsellor to his first cousin, James IV of Scotland and helped to arrange his marriage to Princess Margaret Tudor of England. As a reward he was created Earl of Arran in 1503. The local economy for much of this period was based on the run rig system, the basic crops being oats, barley and potatoes. The population slowly grew to about 6,500. In the early 19th century Alexander, 10th Duke of Hamilton (1767–1852) embarked on a programme of clearances that had a devastating effect on the island's population. These "improvements" typically led to land that had been rented out to as many as 27 families being converted into a single farm. In some cases, land was promised in Canada for each adult emigrant male. In April 1829, for example, 86 islanders boarded the brig Caledonia for the two-month journey, half their fares being paid for by the Duke. However, on arrival in Quebec only 41 ha was made available to the heads of extended families. Whole villages were removed and the Gaelic culture of the island devastated. The writer James Hogg wrote, "Ah! Wae's [Woe is] me. I hear the Duke of Hamilton's crofters are a'gaun away, man and mother's son, frae the Isle o' Arran. Pity on us!". A memorial to this has been constructed on the shore at Lamlash, paid for by a Canadian descendant of the emigrants.

Goatfell was the scene of the death of English tourist Edwin Rose who was allegedly murdered by John Watson Laurie in 1889 on the mountain. Laurie was sentenced to death, later commuted to a life sentence and spent the rest of his life in prison.

On 10 August 1941 a RAF Consolidated B-24 Liberator LB-30A AM261 was flying from RAF Heathfield in Ayrshire to Gander International Airport in Newfoundland. However, the B-24 crashed into the hillside of Mullach Buidhe north of Goat Fell, killing all 22 passengers and crew.

Geography

The island lies in the Firth of Clyde between Ayr and Ardrossan, and Kintyre. The profile of the north Arran hills as seen from the Ayrshire coast is referred to as the "Sleeping Warrior", due to its resemblance to a resting human figure. The highest of these hills is Goat Fell at 875 m. There are three other Corbetts, all in the north east: Caisteal Abhail, Cìr Mhòr and Beinn Tarsuinn. Beinn Bharrain is the highest peak in the north west at 721.4 m.

The largest glen on the island is Glen Iorsa to the west, whilst narrow Glen Sannox (Gaelic: Gleann Shannaig) and Glen Rosa (Gaelic: Gleann Ròsa) to the east surround Goat Fell. The terrain to the south is less mountainous, although a considerable portion of the interior lies above 350 m, and A' Chruach reaches 512.5 m at its summit. There are two other Marilyns in the south, Tighvein and Mullach Mòr (Holy Island).

Villages

Arran has several villages, mainly around the shoreline. Brodick (old Norse: 'broad bay') is the site of the ferry terminal, several hotels, and the majority of shops. Brodick Castle is a seat of the Dukes of Hamilton. Lamlash, however, is the largest village on the island and in 2001 had a population of 1,010 (1,100 mid-2020 est.) compared to 621 for Brodick. Other villages include Lochranza and Catacol in the north, Corrie in the north east, Blackwaterfoot and Kilmory in the south west, Kildonan in the south and Whiting Bay in the south east.

Surrounding islands

Arran has three smaller satellite islands: Holy Island lies to the east opposite Lamlash, Pladda is located off Arran's south coast and tiny Hamilton Isle lies just off Clauchlands Point 1.2 km north of Holy Island. Eilean na h-Àirde Bàine off the south west of Arran at Corriecravie is a skerry connected to Arran at low tide. Ailsa Craig is situated south east of Arran and on a clear day is visible from most of Arran's south coast.

Other islands in the Firth of Clyde include Bute, Great Cumbrae and Inchmarnock.

Geology

The division between the "Highland" and "Lowland" areas of Arran is marked by the Highland Boundary Fault which runs north east to south west across Scotland. Arran is a popular destination for geologists, who come to see intrusive igneous landforms such as sills and dykes, and sedimentary and meta-sedimentary rocks ranging in age from Precambrian to Mesozoic.

Most of the interior of the northern half of the island is taken up by a large granite batholith that was created by substantial magmatic activity around 58 million years ago in the Paleogene period. This comprises an outer ring of coarse granite and an inner core of finer grained granite, which was intruded later. This granite was intruded into the Late Proterozoic to Cambrian metasediments of the Dalradian Supergroup. Other Paleogene igneous rocks on Arran include extensive felsic and composite sills in the south of the island, and the central ring complex, an eroded caldera system surrounded by a near-continuous ring of granitic rocks.

Sedimentary rocks dominate the southern half of the island, especially Old and New Red Sandstone. Some of these sandstones contain fulgurites – pitted marks that may have been created by Permian lightning strikes. Large aeolian sand dunes are preserved in Permian sandstones near Brodick, showing the presence of an ancient desert. Within the central complex are subsided blocks of Triassic sandstone and marl, Jurassic shale, and even a rare example of Cretaceous chalk. During the 19th century barytes was mined near Sannox. First discovered in 1840, nearly 5,000 tons were produced between 1853 and 1862. The mine was closed by the 11th Duke of Hamilton on the grounds that it "spoiled the solemn grandeur of the scene" but was reopened after the First World War and operated until 1938 when the vein ran out.

Visiting in 1787, the geologist James Hutton found his first example of an unconformity to the north of Newton Point near Lochranza, which provided evidence for his Plutonist theories of uniformitarianism and about the age of the Earth. This spot is one of the most famous places in the study of geology.
