At the heart of the financial world for which London is famous is Threadneedle Street and an area of the capital that is simply known as The City. This is where the Bank of England, with its fascinating museum, is located and not far away in Paternoster Square is the London Stock Exchange. Apart from the financial aspect, there is also St Paul's Cathedral close by, making a visit to this historic part of London a 'must-do' on any trip.
