What do you know about the history of london

London is a very old city. It began life two thousand years ago as a Roman fortification at a place where it was possible to cross the river Thames. Around the town the Romans built wall for defence.  After the Norman Conquest there was a long period of peace, during which people began building outside  the walls. This building continued for a very long time, so that in a few centuries London covered a very large territory.  In 1665,  during the terrible plague in London, many people left the city. In 1666 the Great Fire of London ended the plague, but it also destroyed much of the city. After it London was rebuilt and people returned to it.
