 However , he left a still greater legacy to the city of Glasgow . At some point between the years 1175 and 1178 , Jocelin obtained from King William a grant of burghal status for the settlement of Glasgow , with a market every Thursday . The grant of a market was the first ever official grant of a weekly market to a burgh . Moreover , between 1189 and 1195 , King William granted the burgh an annual fair , a fair still in existence today , increasing Glasgow 's status as an important settlement . As well as new revenues for the bishop , the rights entailed by Glasgow 's new burghal status and market privileges brought new people to the settlement , one of the first of whom was one Ranulf de Haddington , a former burghess of Haddington . The new settlement was laid out ( probably under the influence of the burgh of Haddington ) around Glasgow Cross , down the hill from the cathedral and old fort of Glasgow , but above the flood level of the River Clyde .
