Islay (/ˈaɪlə/ EYE-lə; Scottish Gaelic: Ìle, Scots: Ila) is the southernmost island of the Inner Hebrides of Scotland. Known as "The Queen of the Hebrides", it lies in Argyll and Bute just south west of Jura and around 40 kilometres (22 nautical miles) north of the Northern Irish coast. The island's capital is Bowmore where the distinctive round Kilarrow Parish Church and a distillery are located. Port Ellen is the main port.
Islay is the fifth-largest Scottish island and the eighth-largest island of the British Isles, with a total area of almost 620 square kilometres (240 sq mi). There is ample evidence of the prehistoric settlement of Islay and the first written reference may have come in the first century AD. The island had become part of the Gaelic Kingdom of Dál Riata during the Early Middle Ages before being absorbed into the Norse Kingdom of the Isles.
The later medieval period marked a "cultural high point" with the transfer of the Hebrides to the Kingdom of Scotland and the emergence of the Clan Donald Lordship of the Isles, originally centred at Finlaggan. During the 17th century the power of Clan Donald waned, but improvements to agriculture and transport led to a rising population, which peaked in the mid-19th century. This was followed by substantial forced displacements and declining resident numbers.
