Iona Island Scotland antique print. Iona (Scottish Gaelic: Ì Chaluim Chille) is a small island in the Inner Hebrides off the Ross of Mull on the western coast of Scotland. It was a centre of Gaelic monasticism for four centuries and is today known for its relative tranquility and natural environment. It is a tourist destination and a place for spiritual retreats. Its modern Gaelic name means “Iona of (Saint) Columba” (formerly anglicised “Icolmkill”). Iona lies about 2 kilometres (1 mi) from the coast of Mull. It is about 2 kilometres (1 mi) wide and 6 kilometres (4 mi) long with a resident population of 125. The geology of the island consists mainly of Precambrian Lewisian gneiss with Torridonian sedimentary rocks on the eastern side and small outcrops of pink granite on the eastern beaches. Like other places swept by ocean breezes, there are few trees; most of them are near the parish church. Iona’s highest point is Dùn Ì, 101 metres (331 ft), an Iron Age hill fort dating from 100 BC – AD 200. Iona’s geographical features include the Bay at the Back of the Ocean and Càrn Cùl ri Éirinn (the Hill/Cairn of [turning the] Back to Ireland), said to be adjacent to the beach where St. Columba first landed. The main settlement, located at St. Ronan’s Bay on the eastern side of the island, is called Baile Mòr and is also known locally as “The Village”. The primary school, post office, the island’s two hotels, the Bishop’s House and the ruins of the Nunnery are here. The Abbey and MacLeod Centre are a short walk to the north. Port Bàn (white port) beach on the west side of the island is home to the Iona Beach Party. There are numerous offshore islets and skerries: Eilean Annraidh (island of storm) and Eilean Chalbha (calf island) to the north, Rèidh Eilean and Stac MhicMhurchaidh to the west and Eilean Mùsimul (mouse holm island) and Soa Island to the south are amongst the largest.
