The Great Fire of London occurred in September 1666 and lasted for four days. It began in a bakery on Pudding Lane and quickly spread through the wooden buildings of the city. The fire destroyed a large part of London, including around 13,200 houses, 87 parish churches, and several important buildings like St. Paul's Cathedral. Despite the extensive damage, the death toll was surprisingly low, with only a few recorded fatalities. The fire led to significant changes in building regulations and urban planning, promoting the use of brick and stone instead of wood to prevent future disasters.
