This article deals with the history of the city of Glasgow, Scotland. See also Timeline of Glasgow history. Founding of the city The present site of Glasgow has been settled since prehistoric times, being the furthest downstream fording point of the River Clyde, at its confluence with the Molendinar Burn. The Romans built outposts in the area and constructed the Antonine Wall to keep Roman Britannia separate from Celtic and Pictish Caledonia. Items from the wall, such as altars from Roman forts, including Balmuildy, can be seen in the Hunterian Museum. After the Romans withdrew from Caledonia, the village was part of the large Kingdom of Strathclyde, whose capital was at Dumbarton downstream. It merged in the 9th century with other regions to create the united Kingdom of Scotland.

In the 15th century a private chapel was made to St Machan in the north nave to devolve to the congregation at the death of the founder. Extensions and alterations to the cathedral buildings have continued ever since. The most recent addition was the Millennium Window unveiled on 3 June 1999. After the Scottish Reformation in 1560, the Catholic rituals ended and the Catholic statues and symbols were removed or painted over. The large Cathedral served three different Presbyterian parishes simultaneously. The choir was used by the Inner High parish. The nave was used by the Outer High parish (later named St. Paul's). The crypt was used by Laigh parish. University of Glasgow In 1451, the University of Glasgow was founded by papal bull and established in religious buildings in the precincts of Glasgow Cathedral. By the start of the 16th century, Glasgow had become an important religious and academic city and by the 17th century the university had moved from
