Iona is a small island in the Inner Hebrides of Scotland that has an important place in the history of Christianity in Scotland and is renowned for its tranquility and natural beauty. Its Gaelic name is Ì Chaluim Cille (Saint Columba's Island; formerly anglicised "Icolmkill"), or sometimes just Ì or Idhe.
Iona lies approximately one mile (1.6 km) from the coast of Mull. The island is 1 mile wide (1.6 km) and 3.5 miles (5.6 km) long with a resident population of 125. The island's stone base is covered by a layer of basaltic lava, and like other places swept by ocean breezes. There are few trees, with most of these being located around the parish church area.
