The Great Fire of London

Background

London was still recovering from the plague year of 1665. Inside the old city walls, narrow streets held timber-framed buildings, warehouses, workshops, and combustible goods close together. Parishes kept hooks, ladders, buckets, and simple pumps, but there was no professional municipal fire brigade.

What happened

The fire began around 1 a.m. at Thomas Farriner’s bakery. The precise ignition is unknown; a spark or ember from an oven is a plausible explanation. A dry summer, strong easterly wind, delayed firebreaks, and tightly packed wooden buildings transformed a local fire into a citywide disaster.

Aftermath

Relief, temporary shelter, and the immense work of tracing property claims began immediately. Although ambitious plans proposed rebuilding London on a new grid, legal and financial realities meant that most streets followed their earlier routes.

Long-term consequences

Rebuilding rules favored brick and stone, streets were widened in places, and new institutions for fire insurance and organized firefighting developed. Christopher Wren’s St Paul’s Cathedral and the Monument became permanent landmarks of the reconstructed city.

Significance

The fire shows how building materials, street form, governance, weather, and emergency decisions combine to create urban risk. It also demonstrates that reconstruction can transform safety standards while preserving the underlying geography of a city.

What remains today

The Monument stands near Pudding Lane, and much of the City still follows medieval street alignments. Archaeological evidence, government papers, eyewitness accounts, churches, and the rebuilt St Paul’s make the event legible in today’s landscape.

Uncertainty

The often-repeated official death total is not a reliable measure of all who died. The source of ignition is also not known with certainty. Contemporary accusations against foreign or religious minorities were unsupported and led to persecution.
