London covers 600 square miles and has a population of 8.6 million, but only its oldest part, just one square mile in size, is called the City of London. That is where the Romans founded the city of Londinium shortly after they arrived in 43AD. Today, the City of London – or simply “the City” – is the centre of London’s finance industry. The City is where you find the Bank of England, the London Stock Exchange, the investment banks, insurance companies and financial markets. It combines the most modern headquarters buildings with Roman remains and medieval churches, and it is great to explore on foot.

Many visitors to London like to see the city from on high and several attractions give them the opportunity to do so. The London Eye and the viewing platform at The Shard are two of the capital’s most popular attractions, while One New Change and the Sky Garden attract people who do not wish to pay an entrance fee or wait in line to look at London from high up. Other towers, such as Arcelor Mittal Orbit in the Olympic Park and The Monument to the Great Fire, may not attract so many visitors but are important parts of London’s skyline.
