There are some big tourist attractions in the city. St Paul's Cathedral, The Tower of London, The Old Bailey, The Bank of England, Lloyds Building and Tower 42.

The present St Paul's Cathedral was designed by Christopher Wren as part of the re-building of London after the fire, and the building was eventually completed in 1710.

The Lloyd's Building was designed by Richard Rogers, the same architect that designed the Pompidou Centre in Paris. Opened in 1986, it is one of the most well known modern buildings in London.
