London Before the Fire

By the mid-17th century, London was a bustling but vulnerable city. Its narrow streets and timber-framed houses created a tinderbox environment. Most homes used open flames for cooking and heating, and fire-fighting infrastructure was minimal.

London had survived plagues, wars, and political upheaval, but in 1666, it faced one of its greatest challenges.

Outbreak on Pudding Lane

On September 2, 1666, Thomas Farriner’s bakery on Pudding Lane became the spark. Flames spread quickly, fueled by wooden homes, warehouses of pitch and tar, and strong winds from the east.

Within hours, the fire engulfed entire streets. Londoners panicked, and traditional methods like leather buckets and hand-pumps proved useless.

Day 2–3: Over 13,000 houses and 87 churches were destroyed.

Day 4: Firebreaks, created by blowing up houses with gunpowder, finally halted the spread.
