In 1848 the Honourable George Frederick Boyle (later 6th Earl of Glasgow) set up a choir school attached to the Church of St. Andrews, Millport. In 1849 Boyle founded and endowed the Episcopal College and Collegiate Church of the Holy Spirit, Cumbrae which was completed in 1851 to plans by William Butterfield. The College was consolidated in the 1860s and affiliated to the University of Durham as Cumbrae Theological College. In 1879 the Collegiate Church was elevated to the status of Cathedral of Argyll and the Isles. It closed in 1888, and between 1919 and 1927 the buildings housed the Community of St Andrew of Scotland.
