The Great Fire of London occurred in September 1666 and is remembered as a catastrophic event that devastated a significant portion of the city. It began in a bakery on Pudding Lane and quickly spread, fueled by wooden buildings and the city's narrow streets. The fire lasted for several days, destroying approximately 13,200 houses, St. Paul's Cathedral, and many other significant structures. Though the loss of life is believed to have been relatively low, the fire led to major changes in building regulations and city planning, ultimately transforming London’s landscape and infrastructure.
