                    at the intersection of Gracechurch Street, Cornhill, Bishopsgate 
                    Street and Leadenhall Street. Also showing is St Peter upon 
                    Cornhill and part of Leadenhall near the north end of Gracechurch

                  Cornhill 
                    is one of the city's chief wards, and stands on one of the 
                    major hills of the City (on which formerly stood the Roman 
                    basilica). On this site in ancient times a corn market was 
                    held. It was anciently a very wide street with a market place 
                    aspect . In 1283 Henry de Walleis build a prison on Cornhill 
                    for the incarceration of improper persons (mostly prostitutes). 
                    It was called the Tun-upon-Cornhill after its distinctive 
                    shape which reminded people of a ship of that name. In 1401 
                    the prison was converted into a cistern for sweet water, conveyed 
                    by lead pipes from Tyburn, and was then called the Conduit-on-Cornhill 
                    although the sites remained famous for its stocks and pillory 
                    for hundreds of years afterwards. 
                  By 
                    the seventeenth century Cornhill's market was replaced by 
                    a score of coffee shops for which Cornhill remained noted 
                    until the late nineteenth century.
