The earliest church, dedicated to the Holy Trinity, was part of a monastic foundation established by St Kentigern (more popularly, St Mungo, d. 603) on ground consecrated by St Ninian in the 5th cent. This site is now covered by the Blacader aisle. The diocese of Glasgow was re-established by David I and the first stone building consecrated in 1136 in his presence. It is now crown property, worshipped in by the Church of Scotland in the reformed tradition, under presbyterian government.
