It began life as a Roman fortification at a place where it was possible to cross the River Thames. A wall was built around the town for defence, but during the long period of peace which followed the Norman Conquest, people built outside the walls. This building continued over the years, especially to the west of the city. In 1665 there was a terrible plague in London, so many people left the city and escaped to the villages in the surrounding countryside. In 1666 the Great Fire of London ended the plague, but it also destroyed much of the city. Although people returned to live in the rebuilt city after the plague and the Great Fire, there were never again so many Londoners living in the city centre.
