London is the British capital and one of the biggest cities in the world. London is situated on the river Thames. Its population is over 7 million people. London consists of 3 parts: the City of London, the West End and the East End.
The oldest part of London is called the City. It is small, but it is very important. Thousands of people come here every morning to work in large offices.
There are some famous buildings in the City, such as St Paul's Cathedral and the Tower of London which was built nine centuries ago and used as a royal palace, a fortress, and a political prison. Now it is a museum.
