In 1666 the City of London was a random cluster of close-packed houses, mostly timber-framed, arranged in narrow streets and alleyways where rich and poor lived in close proximity. Large areas were slum tenements.
Some parts of the City had changed little since mediaeval times, and all manner of noxious trades took place, often from the same buildings within which the traders and craftsmen lived.
Although Londoners were well-used to fires, a long, hot summer, a sudden period of strong winds, and a fire breaking out late at night were all that was needed to start the worst fire Britain had ever seen. Here we present all of the key details of the Great Fire, the people involved, and the aftermath.
