A collegiate foundation

George Frederick Boyle, later sixth Earl of Glasgow, commissioned William Butterfield to design a church and associated college buildings. Construction began in 1849 and the foundation opened in 1851. The church became a cathedral in 1876, making this small island town a seat of the Scottish Episcopal diocese of Argyll and the Isles.

Church and residence together

The composition joins a steep spire and pointed church windows to an adjoining residential range. Chimneys, dormers and a turret distinguish the domestic accommodation without breaking the Gothic character of the whole. The surviving ensemble matters as a collegiate foundation, rather than simply as an isolated church tower.

Layers of island history

The heritage trail also records early carved stones associated with Kirkton and a cross found at the Garrison. Their presence here should not be taken as proof that this nineteenth-century building occupies their original setting. Historic Environment Scotland lists the cathedral and collegiate buildings at Category A. Check the institution’s own arrangements before seeking interior access.

Colour and the chancel

The church-supplied account published by the National Churches Trust identifies a carved stone cross within the arch separating nave and chancel. Behind the choir, red, yellow and blue geometric tiles contrast with dark timber, while the chancel ceiling depicts island ferns and wild flowers. Glass by William Wailes and John Hardman adds another layer of colour. These features explain how Butterfield’s relatively small church achieves an elaborate liturgical focus within the larger collegiate ensemble.
