Cheapside is a street in the City of London, the historic and modern financial centre of London, which forms part of the A40 London to Fishguard road. It links St. Martin's Le Grand with Poultry. Near its eastern end at Bank junction, where it becomes Poultry, is Mansion House, the Bank of England, and Bank station. To the west is St. Paul's Cathedral, St. Paul's tube station and Paternoster Square.
In the Middle Ages, it was known as Westcheap, as opposed to Eastcheap, another street in the City, near London Bridge. The boundaries of the wards of Cheap, Cordwainer and Bread Street run along Cheapside and Poultry; prior to boundary changes in 2003 the road was divided amongst Farringdon Within and Cripplegate wards in addition to the current three.
The contemporary Cheapside is widely known as the location of a range of retail and food outlets and offices, as well as the City's only major shopping centre, One New Change.(Wikipedia)
