Inchmarnock

Inchmarnock is a privately owned island at the northern end of the Sound of Bute in the Firth of Clyde on Scotland’s west coast. It lies west of the Isle of Bute and stretches about 3.5 kilometres long, rising to 60 metres at its highest point. The island has a single ridge running north to south, is partly wooded, and contains two small inland lochans. Sea caves open at both northern and southern ends, and a reef called Tràigh na h-Uil lies along the west coast. Inchmarnock Water, the channel between the island and the Kintyre peninsula, links the Sound of Bute to Loch Fyne and the Kyles of Bute. The island’s name comes from the Gaelic Innis Mheàrnaig, meaning Island of Marnock. Saint Marnock, a 7th-century holy man, lived here and founded a monastery. A Bronze Age cist near the northern end once held the remains known as the Queen of the Inch, now displayed under glass. During World War II the 9th Scottish Commando and French Canadians trained on Inchmarnock for D-Day landings. In 1999 Lord Smith of Kelvin bought the island and restored the land, introducing a herd of 230 Highland cattle. A seven-year archaeological project uncovered an early monastic enclosure and workshops around the medieval church at Midpark. Excavations revealed hundreds of inscribed slates from the 8th or 9th century, including practice writing, ogham script and Latin texts. One notable find, the Hostage Stone, shows four human figures, a boat and marks that may depict slave-raiding or a religious procession. Today the island operates as an organic farm and hosts the largest colony of herring gulls in the Firth of Clyde, alongside wintering greylag geese.
