The hill from which it takes its name is one of the three ancient hills of London; the others are Tower Hill, site of the Tower of London, and Ludgate Hill, crowned by St Paul's Cathedral. The highest point of Cornhill is at 17.7 metres (58 ft) above sea level.[1]
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.[2][3] This became the mark from which many distances to and from London were measured and the name still appears on older mileposts (but see also the nearby London Stone and St. Mary-le-Bow church).
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".[4]
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.[5][6]
