Cornhill is one of the traditional divisions of the City. The street contains two of the City churches designed by Sir Christopher Wren: St. Michael, Cornhill, and St Peter upon Cornhill, reputed to occupy the oldest Christianised site in London. Both are on the site of the Roman forum of Londinium. At its other end it meets Threadneedle Street, Poultry, Lombard Street and others at Bank junction. Sir Thomas Gresham's original Royal Exchange fronted onto Cornhill, but its successor on the site, designed by William Tite, faces towards the Bank of England across the junction with Threadneedle Street. The "Standard" near the junction of Cornhill and Leadenhall Street was the first mechanically pumped public water supply in London, constructed in 1582 on the site of earlier hand-pumped wells and gravity-fed conduits. The mechanism, a force pump driven by a water wheel under the northernmost arch of London Bridge, transferred water from the Thames through lead pipes to four outlets. The service was discontinued in 1603. This became the mark from which many distances to and from London were measured and the name still appears on older mileposts. In 1652, Pasqua Rosée, possibly a native of Ragusa, Italy, opened London's first coffeehouse, in St. Michael's Alley off Cornhill. The publishers Smith, Elder and Co, based at No. 65, published the popular literary journalCornhill Magazine from 1860 to 1975, as well as the Dictionary of National Biography. The magazine was first edited by William Makepeace Thackeray. In Charles Dickens' A Christmas Carol, Bob Cratchit slides down Cornhill 20 times in honour of it being Christmas Eve.
Contemporary Cornhill
Today, the street is commonly associated with opticians and makers of optical apparatus such as microscopes and telescopes. A statue of the engineer James Henry Greathead was erected in 1994 in the road beside the Royal Exchange, which lies within the ward. Underneath the modern pavement is the world's first underground public toilet, which opened in 1855. Users were charged a standard fee of 1d, reputedly giving rise to the saying to "spend a penny". Cornhill formed part of the marathon course of the 2012 Olympic and Paralympic Games. The women's Olympic marathon took place on 5 August and the men's Olympic marathon on 12 August. The four Paralympic marathons were held on 9 September. The postcode for the street is EC3V.
