The Great Fire of London, with Ludgate and Old St. Paul's," painted c. 1670, four years after the fire.

“Ignis aurum probat, miseria fortes viros.”

- Seneca, 64 A.D.

Fire tests gold. Adversity tests strong men.

Sixteen centuries later, London skipped the philosophy seminar and got the Great Fire.

September 1666.

Four days. Thirteen thousand houses incinerated. Eighty-seven churches. The Guildhall. Old St. Paul’s, reduced to a scorched, roofless shell.

Nearly the whole walled city turned to ash in ninety-six hours.

The official death count: six or eight people. Neil Hanson, a historian who’s studied the fire closely, thinks that’s wrong. The fire burned hot enough to cremate a body outright, and nobody was counting the poor.

Whatever the body count, most of the city’s housing and businesses were burned to the ground.

John Evelyn watched the disaster and wrote:

“The stones of Paules flew like granados, the melting lead running down the streets in a stream, and the very pavements glowing with fiery redness.”

London needed to grieve, but first, it went hunting for vengeance.

A Culprit London Could Hang

Everyone knew where the flames started.

A baker named Thomas Farriner. An oven on Pudding Lane, its embers not properly banked (raked over and covered to smolder low overnight) before he retired to bed.

Sparks from the embers caught kindling in a house built of timber. A hot, dry summer behind it. A hard east wind pushing it forward.

London was a firetrap waiting for a spark.

Nobody knew in the days after the fire, though.

Farriner swore he didn’t start it, and nobody could prove he lied. An accident nobody could pin on him wasn’t the story London demanded, anyway.

The year on the calendar:

1666.

Preachers didn’t need much convincing. Six-six-six, right there on the calendar. This was the end. An entire city incinerated doesn’t wait for an investigation. It wants a villain, and an accident won’t do.

London got its innocent man: Robert Hubert, a French watchmaker.

He confessed to what everyone already suspected: a plot, deliberate, foreign hands behind it. Even the judge didn’t believe a word. Hubert’s story kept changing, and something about him read as broken rather than guilty.

Irrelevant. A confession was a confession.

The mob walked him to Tyburn through streets still smelling of smoke, past a crowd big enough to fill the gallows field.

Hubert was hanged there. His body didn’t survive the walk to the surgeons afterward. The crowd tore it apart first.

He did nothing. And he died anyway.

Thomas Farriner walked away unscathed. He even signed the bill that hanged Hubert, then went right on baking navy bread from a shop a few hundred feet from where the body came apart.

What the Monument Doesn’t Say

The Monument, City of London. 202 feet tall — exactly the distance to the spot on Pudding Lane where the fire began.

Walk to the spot where it started in 2026, and you’ll find a column, not a plaque.

Wren built it between 1671 and 1677, a fluted Doric shaft topped with a gilded urn shaped like a flame. It stands 202 feet tall. That number isn’t decorative.

Lay the column on its side, pointed east, and it lands exactly on Pudding Lane, right where Farriner’s bakery stood. Wren measured the memorial to the fire itself, not to any person.

Three hundred and eleven steps take you to a viewing platform near the top, one of the most impressive views in the old City.

For decades after it went up, the inscription on its base blamed the fire on “the treachery and malice of the Popish faction,” official language, carved in stone, that stayed there until 1830, more than 150 years after everyone involved was dead.

Nowhere on that column is the hanged Robert Hubert’s name. Thomas Farriner’s isn’t there either.

The other signed the paper that hanged an innocent man, then went back to baking bread for the Royal Navy.

The Monument marks the fire’s location. It doesn’t mark who paid his life for it.
