The fire destroyed much of the city and caused widespread panic and destruction. It is estimated that around 70,000 of the city's 80,000 residents were left homeless. The fire raged for four days and destroyed over 13,000 homes, as well as many public buildings, including St Paul's Cathedral. The Great Fire of London is considered one of the most significant events in the city's history.
