Early history

The area around Glasgow has hosted communities for millennia, with the River Clyde providing a natural location for fishing. The Romans later built outposts in the area and, to protect Roman Britannia from the Brittonic speaking (Celtic) Caledonians, constructed the Antonine Wall. Items from the wall, such as altars from Roman forts like Balmuildy, can be found at the Hunterian Museum today.

Glasgow itself was reputed to have been founded by the Christian missionary Saint Mungo in the 6th century. He established a church on the Molendinar Burn, where the present Glasgow Cathedral stands, and in the following years Glasgow became a religious centre.Glasgow grew over the following centuries. The Glasgow Fair reportedly began in 1190. A bridge over the River Clyde was recorded from around 1285, where Victoria Bridge now stands. As the lowest bridging point on the Clyde it was an important crossing. The area around the bridge became known as Briggait. The founding of the University of Glasgow adjoining the cathedral in 1451 and elevation of the bishopric to become the Archdiocese of Glasgow in 1492 increased the town's religious and educational status and landed wealth. Its early trade was in agriculture, brewing and fishing, with cured salmon and herring being exported to Europe and the Mediterranean. By the fifteenth century the urban area stretched from the area around the cathedral and university in the north down to the bridge and the banks of the Clyde in the south along High Street, Saltmarket and Bridgegate, crossing an east–west route at Glasgow Cross which became the commercial centre of the city.
