By the later 12th century Glasgow’s population had reached around 1,500, making it an important settlement. In 1175, Bishop Jocelyn secured a charter from King William making Glasgow a burgh of barony, opening up its doors to trade. In 1238 work began on Glasgow Cathedral, symbolising the city’s growing role as a major ecclesiastical centre.
In 1450 James II issued a chapter to the Bishop “erecting all his patrimony into a regality”. Glasgow was now a Royal Burgh in all but name. Later that same year Glasgow Green became Glasgow’s first public park. In the following year, 1451, the University of Glasgow was founded by Bishop Turnbull at its original site in the High Street, making it the second oldest university in Scotland and the fourth oldest in the UK. In 1471 Provand’s Lordship (pictured), Glasgow’s oldest house, was built, directly opposite the Cathedral building.
Elevated to an archbishopric in 1492, Glasgow, by the end of the 15th century had become a powerful academic and ecclesiastical centre rivalled only by St Andrew’s.
