Architectural historian John Grundy this week enjoys the pleasures of shops and shopping and traces their history from medieval market to modern shopping mall.Dressed as a medieval jester, John begins the story in Newcastle's Sunday Quayside Market - the kind of place where shopping has been done since the beginning of towns. The programme then traces the history of the shop-front, from plain shutters that let down to form a counter during the day to the culmination of shop-front design in the ornamental windows of Victorian times with their brackets, friezes and cornices. Medieval shop designs still survive in The Close beneath the High Level Bridge, Georgian windows abound in Durham's Saddler Street, and Victorian shop-fronts still exist everywhere.This programme was shot entirely in Newcastle and Durham City, where the whole development of shop styles can be found. John takes a look at electronic shopping, department stores (Bainbridge in Newcastle was one of the first in the world), arcades and shopping malls. And he ends the programme with his admiration of modern shops like Newcastle's French Connection - "the elegant simplicity, the white walls and the pale wood, set against the hi-tech engineering of smooth steel and glass."
