Saint Ninian
The Diocese of Glasgow and Galloway is a union of two of the oldest dioceses in Scotland. The Diocese of Galloway (also known as Candida Casa or Whithorn) is thought to have been founded by Saint Ninian in the 5th century. The Diocese of Glasgow is thought to have been founded by Saint Mungo (or Kentigern) around 550. On 9 January 1492, the Diocese of Glasgow was raised in rank to be an archdiocese.
