Iona is an island in the Inner Hebrides, off the Ross of Mull on the western coast of Scotland. It is mainly known for Iona Abbey, though there are other buildings on the island. Iona Abbey was a centre of Gaelic monasticism for three 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 Scottish Gaelic name means "Iona of (Saint) Columba" (formerly anglicised as "Icolmkill"). Iona's resident population is about 180. In March 1980, the Hugh Fraser Foundation donated much of the main island (and its off-lying islands) to the current owner, the National Trust for Scotland. The abbey and some church buildings are owned by the Iona Cathedral Trust.
