On a small island in Loch Finlaggan, in the northeast of Islay, you can still see the foundations of the buildings where the Lords of the Isles held court between roughly 1336 and 1493. From here, the MacDonalds ran a semi-independent maritime realm that ran from Lewis to Kintyre, with its own legal code, its own bishops, its own diplomatic relations with England and France. Successive chiefs were proclaimed Lord of the Isles at Finlaggan, standing barefoot on a seven-foot-square coronation stone with footprint impressions carved into it, anointed by the Bishop of Argyll and seven priests. Their Council of the Isles met on an even smaller island in the same loch, Eilean na Comhairle, in a timber-framed crannog originally built in the first century BC. The Islay Charter of 1408, recording a grant of land from Domhnall of Islay to Brian Vicar MacKay, is one of the earliest surviving examples of Scottish Gaelic in formal public use. In 1493 James IV forfeited the title, ordered Finlaggan razed, had the coronation stone destroyed. The Lordship ended. Islay was demoted to a remote Scottish county. The buildings on the island in the loch slumped slowly into the grass.

Modern Islay's most famous export emerged in the eighteenth and nineteenth centuries when farmers, who had always distilled small batches of whisky for personal use, were taxed and regulated into commercial production. The peat that smokes the malted barley grows in the bogs of the interior; the soft water comes off the same hill burns that filled the household stills; the maritime air gives the spirit something else, something harder to name. Today Islay's distilleries cluster in three groups. The south coast - Laphroaig, Lagavulin, Ardbeg, and now the reopened Port Ellen - produces the heavily peated whiskies that taste like seaweed and creosote and bonfire smoke. The east coast at Caol Ila and Bunnahabhain produces lighter, more elegant spirits. The west and centre, with Bowmore, Bruichladdich, Kilchoman, and Ardnahoe, sit somewhere in between. Each has a story. Each is now a destination. Every year for one week in May the Feis Ile - the Islay Festival of Malt and Music - turns the entire island into a single rolling tasting event with bands in every village hall.

Islay was a Gaelic-speaking island for fourteen hundred years. As late as 1881 around 80 percent of islanders spoke Gaelic as their first language. By the 2011 census the figure had fallen to about 17 percent, with most fluent speakers over sixty. The decline mirrors that of every other Inner Hebridean island and has the same causes: economic emigration, English-medium education, the loss of monolingual Gaelic households where children grew up immersed in the language without effort. The recovery, where there is one, is grassroots and recent. Ionad Chaluim Chille Ile, the Columba Centre at Bowmore, was opened in 2002 as a Gaelic-language and culture institution; primary-age Gaelic immersion units operate in several Islay schools; the Feis Ile increasingly involves Gaelic music and song. The current generation of Gaelic learners on Islay are mostly enthusiasts and incomers; the next will inherit whatever they manage to build. The language is not dead. It is also not what it was a century ago.

Every October roughly 35,000 barnacle geese and a smaller number of Greenland white-fronted geese fly from breeding grounds in Greenland and Spitsbergen and land on Islay. The whole world population of one of these subspecies - the Greenland barnacle goose - winters in Scotland and northern Ireland, and a large fraction of them choose this one island. They stay until April. For six months the fields around Loch Indaal and the Rinns are alive with grey-and-white birds the size of small dogs, calling to each other in voices that carry for miles. The geese eat the grass; the farmers have an arrangement with the government and the RSPB that compensates them for the lost grazing. The geese leave in spring; the cattle come back. Birdwatchers visit Islay specifically for the geese, and for the larger story they tell about migration corridors. The same island that exports millions of bottles of whisky to Tokyo and New York receives, for free, a sky full of birds every autumn. The trade balance does not favour the geese.

Islay's permanent population is around 3,000 today, down from a peak of about 15,000 before the Highland Clearances of the nineteenth century, when landowners cleared tenant farmers to make way for sheep and many were forced to emigrate to the United States and Canada. Today the island has a small hospital, a high school, two ferry terminals at Port Ellen and Port Askaig, an airport at Glenegedale (EGPI) with daily flights to Glasgow, and the maritime infrastructure that any active Hebridean community needs - lifeboat station, harbours, fishing fleet. Two American World War I troopships went down off the Mull of Oa in 1918; their dead are buried in the Kilchoman cemetery, and a tall American memorial stands on the headland above. The Kildalton High Cross, an eighth-century Celtic stone cross at the old chapel near Ardbeg, is one of the finest pieces of early Christian sculpture in Scotland. The island has been continuously inhabited since the end of the last ice age, when the first stone-tool makers arrived from somewhere on the European continent. The pigs at Howburn Farm dug some of their tools up in 2015. None of this is on the standard distillery tour.
