The Great Fire of London was a large and destructive fire that began at the bakery of Thomas Farriner on Pudding Lane. The fire swept through the central parts of the English city of London from 2 September to 5 September 1666. The fire gutted the medieval City of London consuming 13,200 houses, 87 parish churches, St Paul's Cathedral, and most of the buildings of the City authorities. It is estimated to have destroyed the homes of 70,000 of the City's 80,000 inhabitants. A melted piece of pottery on display at the Museum of London, found by archaeologists in Pudding Lane, shows that the temperature reached 1700 °C.
