Striding across the picture in different directions, two office workers: A lady in a red coat whose head and identity is lost in shadow, and a man wearing a dark suit whose stride is purposeful and confident. A third person, another man, leans against a wall looking thoughtfully into the distance. There is more shadow than highlight in this scene taken at Broadgate, a private estate of financial institutions and global businesses in the heart of the City of London. There are no spring leaves on the trees whose shadows are falling on an opposite wall. The headless lady looks sinister minus her face and there is tension in this image of linear and diagonal space. The City of London has a resident population of under 10,000 but a daily working population of 311,000. The City of London is a geographically-small City within Greater London, England. The City as it is known, is the historic core of London from which, along with Westminster, the modern conurbation grew. The City's boundaries have remained constant since the Middle Ages but it is now only a tiny part of Greater London. The City of London is a major financial centre, often referred to as just the City or as the Square Mile, as it is approximately one square mile (2.6 km) in area. London Bridge's history stretches back to the first crossing over Roman Londinium, close to this site and subsequent wooden and stone bridges have helped modern London become a financial success.
