The Cathedral of The Isles and Collegiate Church of the Holy Spirit is a cathedral of the Scottish Episcopal Church in the town of Millport on the Isle of Cumbrae. It is one of the two cathedrals of the Diocese of Argyll and the Isles, the other being St John's Cathedral in Oban. The ordinary of the diocese is the Right Reverend Kevin Pearson.
George Boyle, 6th Earl of Glasgow was benefactor of the cathedral and commissioned William Butterfield to design the building. Butterfield was one of the great architects of the Gothic revival and also designed St Ninian's Cathedral in Perth. Construction finished in 1849 and the cathedral opened in 1851. Formal gardens and woodland surround the cathedral, the tallest building on Great Cumbrae and the smallest cathedral in the British Isles.
Celtic Crosses at the Cathedral of the Isles.
In the entrance porch is an interesting collection of Celtic crosses, all of which were excavated on the island in Victorian times.
