The oldest part of London with buildings dating back nearly 100 years, the City has been the financial heart of London (and of Europe) foir many years now. The area comprimises only one square mile but is home to the offices of some of the countries leading financial institutions, barristers and insurance companies. It was here in 1666 that the Great Fire of London started in a bakery shop in Pudding Lane. Because of the small size of the area and the cost of real estate, there is very little residents here so, if you're planning to visit the City - which is highly recommended - make sure you do this during the day as there is practically nothing open here in the evening!
