Coordinates: 54°13′34″N 4°41′53″W / 54.22620°N 4.6981°W
The Diocese of the Isles, also known as the Diocese of Sodor, was one of the thirteen dioceses of medieval Scotland. The original seat of the bishopric appears to have been at Peel, on St Patrick's Isle, where indeed it continued to be under English overlordship; the Bishopric of the Isles as it was after the split was relocated to the north, firstly Snizort and then Iona.
The diocese in its full form included the Outer Hebrides, most of the Inner Hebrides (including Iona, Skye, Raasay, Canna, Eigg, Coll, Tiree, Mull, Colonsay, Islay, Jura, Gigha - but not Lismore, Kerrera, Seil or Luing, all under the Bishop of Argyll), the Isle of Bute and the Isle of Arran, as well as the Isle of Man (Mann). The diocese may have originally contained Galloway, a suggestion thought to explain the possible attacks of Wimund on Bishop Gilla Aldan of Whithorn.
