Glasgow Cathedral () is a parish church of the Church of Scotland in Glasgow, Scotland. It is the oldest cathedral in mainland Scotland and the oldest building in Glasgow. The cathedral was the seat of the Archbishop of Glasgow, and the mother church of the Archdiocese of Glasgow and the Province of Glasgow, until the Scottish Reformation in the 16th century. Glasgow Cathedral and St Magnus Cathedral in Orkney are the only medieval cathedrals in Scotland to have survived the Reformation virtually intact. The medieval Bishop's Castle stood to the west of the cathedral until the 18th century. The cathedral is dedicated to Saint Mungo, the patron saint of Glasgow, whose tomb lies at the centre of the building's Lower Church. The first stone cathedral was dedicated in 1136, in the presence of David I. Fragments of this building have been found beneath the structure of the present cathedral, which was dedicated in 1197, although much of the present cathedral dates from a major rebuilding in the 13th century. Following its foundation in 1451, the University of Glasgow held its first classes within the cathedral's chapter house. After the Reformation, Glasgow Cathedral was internally partitioned to serve three separate congregations (Inner High, Outer High and Barony). The early 19th century saw a growing appreciation of the cathedral's medieval architecture, and by 1835 both the Outer High and Barony congregations had moved elsewhere in the city, allowing the restoration of the cathedral to something approaching its former glory. Glasgow Cathedral has been Crown property since 1587. The entire cathedral building passed into the care of the state in 1857, and today it is the responsibility of Historic Environment Scotland. The congregation is today part of the Church of Scotland's Presbytery of Glasgow. History Early history The history of Glasgow Cathedral is closely linked with that of the city. In the 6th century Saint Mungo is said to have brought the body of a holy man, Fergus, for burial at a site named Cathures (which came to be known as Glasgow). Saint Ninian is reputed to have dedicated the burial ground there on the western bank of the Molendinar Burn in the 5th century (the cathedral's Blacader Aisle may mark this site). Mungo built a monastic cell in the burial ground, and was buried in his church there in 614. His shrine in the Lower Church of Glasgow Cathedral was an important
