What London REALLY Looked Like Before the Great Fire of 1666

You think you know London. The stone, the domes, the great cathedral that has watched the Thames for centuries. But that London came second. The first was built of timber and tar. A wooden maze where the houses leaned so close that neighbours could almost shake hands across the lane. And in just four days of September 1666, the heart of it burned to ash and never came back. I'm Arthur, and these streets are gone now. So walk them with me one last time. Begin in the year 1600. London is already old. A thousand-year-old city, wearing the bones of the Roman town that first founded it. But it has long outgrown them. The walls the Romans left still ring its centre, and London has burst straight through them, spilling along the river in every direction. Inside, it is a city of wood, houses of oak frame and lime plaster, roofs of straw thatch sealed with pitch, packed so close together that a cart can barely pass between them. There is no plan to any of it. The streets simply grew, lane folding into lane, the way a forest grows. And it is filling up at astonishing speed. In 1600, perhaps 200,000 people live here. Within 50 years, that number has doubled. London is a magnet, pulling in the young, the hungry and the hopeful from every corner of England, far more than the old city can hold. With nowhere left to spread, it grows the only way it can, inward and upward. Stories stacked upon timber story until the buildings seemed to close over the streets like the canopy of a wood. It is the richest, loudest, most crowded place in the kingdom, and every beam of it, every shingle, every barrel of tar and every cellar is fuel. This is the secret hidden beneath all its glory. London in the 17th century is a masterpiece and a tinderbox, a city that has been quietly, patiently building itself a funeral pyre for a thousand years. Before the spark comes, walk its streets with me, because almost nothing you are about to see is still standing today. Step in through one of the old gates and the city swallows you. The lanes are narrow, often no wider than a man with his arms outstretched, and overhead the buildings close in. Floor by floor, each story was built to jut out beyond the one below it, a medieval trick called jettying, until the rooftops on either side nearly met above the street. Down at street level, it is dim even at noon. The air is thick with wood smoke and tallow and tanned leather and the river. Signs creak overhead. Every trade has its quarter and every quarter its own sound, the hammer, the loom, the cooper's mallet. And then you reach the water and the greatest wonder of all comes into view, London Bridge. There is only one bridge across the Thames in the entire city and it is unlike any bridge you have ever seen. It runs more than 900 feet, carried on a long row of stone arches, and along its whole length stand houses, not small ones. Shops and homes of six and seven stories crowded so tightly along both edges that the bridge is really a street suspended over the water, a tunnel of timber with the river roaring through the narrow arches beneath. More than a hundred families lived their entire lives upon it. At its southern end stands a gatehouse and for centuries it carried a grim warning. The heads of those executed for treason raised high on iron spikes above the gate. One visitor counted more than 30 of them in a single year. By the time of our story, that old custom is finally fading, but the memory of it hangs over the bridge like a shadow. The river itself is the city's great highway. The streets are choked and slow. The water is fast. Hundreds of boatmen work it, calling out for fares, eastward ho, westward ho, ferrying Londoners up the river and down and across, the way we might hail a cab. And rising above all of it, on the hill at the city's heart, stands the cathedral, Old St. Paul's. Forget the famous dome you know today. That cathedral does not exist yet. This one is older and in some ways even greater. A colossal gothic giant, longer than the church that stands on the spot now, one of the largest in all of Europe. It once carried one of the tallest spires in all of Europe until lightning struck it down in 1561 and it was never rebuilt, leaving the great tower strangely flat, like a titan with its crown removed. In its final decades, the king, Charles I, had a vast classical portico of pale stone grafted onto its western front. The new world bolted directly onto the old. But the strangest thing about Old St. Paul's is what went on inside it. The great nave had become a public thoroughfare. Londoners called it Paul's Walk. People strolled through it to trade and to gossip. Servants were hired there, bargains were struck, and on a busy day a man might lead his horse straight down the aisle. A marketplace, a meeting hall, and a shortcut all inside a working cathedral. A city of pine and pitch, packed this tightly, lived with one quiet fear always at the back of its mind. But it had faced that fear before and survived. We crossed the river to Bankside, the one stretch of ground where the strict rules of the city held no sway and where people came to do all the things the respectable city frowned upon. Taverns, gambling, bear gardens, where crowds roared at brutal spectacles we would never stage today. And standing among them, the playhouses. It was here in 1599 that a company of actors raised a ring of timber open to the sky and called it the Globe. Its stage belonged to a glover's son from the country, a man named William Shakespeare, and upon its boards for a single penny a dock worker could stand shoulder to shoulder with a gentleman and watch kings rise and fall. The Globe itself would give a small sharp warning of what fire could do. In 1613, during a performance of Henry VIII, a cannon was fired for effect and a spark caught the thatched roof. In less than an hour the whole theater burned to the ground. They built it again, but the lessons sat there unheeded. In this city, the line between a spark and a catastrophe was paper thin. This same city also knew how to marvel. In the hardest winters of that age, the cold grew so deep that the Thames itself froze solid bank to bank. And the moment it did, Londoners simply moved out onto it. They pitched tents and stalls across the ice and held a fair upon the frozen river. Skating and games, food and drink, a whole second city raised on water turned to stone. They called them the Frost Fairs, and there were famous ones in 1608 and again in 1621. This was London at its fullest. Brilliant, defiant, gloriously alive. And it was a century in which that same city would witness the unthinkable. On a freezing January morning in 1649, a crowd gathered outside a beautiful building in Whitehall, the Banqueting House. A wooden scaffold had been built against its wall, and through one of its tall windows, stepping out beneath a painted ceiling he had himself commissioned from the great Rubens, came the King of England, Charles I. There, before his own people, he was put to death, the only English king ever tried and executed by his subjects. For a few short years, England had no monarch at all. And there was a darker shadow still to come. Just one year before our story reaches its turning point, in 1665, a plague swept through the streets. The bells tolled without rest. Red crosses were painted on the doors of the sick, like wounds on the face of the city, and beneath them four words, Lord have mercy upon us. The official count was around 68,000 dead. The true number was almost certainly close to 100,000, nearly one Londoner in every five. And then it passed. The city buried its dead, opened its shutters, and breathed again. It believed the worst was behind it. The summer of 1666 was the hottest and driest anyone could remember. For weeks, no rain fell at all. John Evelyn wrote that the heat was so fierce it seemed to scorch the very leaves from the trees and dry up the springs and rivers. The wooden city, baked for months, was drier than it had ever been. Just after midnight on the 2nd of September, in a baker's shop on Pudding Lane, a fire began. It was small at first. The Lord Mayor was woken and brought to look at the modest blaze. He scoffed that a woman could put it out with a bucket and went back to bed. By the time anyone grasped what they were truly facing, it was already too late. Because that night, a strong wind was blowing from the east. It seized the flames and drove them straight into the heart of the timber city, leaping from thatch to thatch, from jutting upper floor to jutting upper floor. The very thing that had made the streets so charming, the houses almost touching overhead, now turned them into a single continuous fuse. Imagine you are there. You wake to a sky glowing orange and a sound like a great wind that never stops. You stumble into the street and so does everyone else. There is no fighting this. You seize what you can carry and run for the river, where the boats are already crammed with families and furniture, people paying anything at all for a place on the water. Through the chaos moves a navy official named Samuel Pepys. He pushes his way to the king himself to warn him, and the king gives the order. Pull down the houses, tear open gaps across the city, starve the fire of its fuel, and Pepys, like everyone, tries to save what he loves that very night in his own garden. He digs a pit and buries his wine and a great round of parmesan cheese. The flames reach London Bridge and seem about to leap the river into Southwark, but the houses at the bridge's northern end had burned in an earlier fire, years before, and had never been rebuilt. That one empty gap halts the fire at the water's edge. The south bank is spared. The medieval heart on the north bank is not. And then the fire comes for the cathedral. The booksellers of the city, certain that those ancient stone walls could never burn, had carried their books and papers down into the crypt beneath Old St. Paul's for safekeeping. The fire found the paper. John Evelyn watched what followed, and what he wrote has never been forgotten. The stones of St. Paul's, he said, flew like grenades. The melting lead ran down the streets in a stream, and the pavements glowed so red that neither man nor horse could tread upon them. Six acres of roof melted away. The spine of the city came crashing down into its own crypt. When the wind finally dropped, four days later, the count was almost beyond belief. Thirteen thousand houses, eighty-seven parish churches, the Royal Exchange, the Guildhall, and Old St. Paul's, all gone. Four hundred acres, around four-fifths of the city inside its ancient walls, reduced to smoking ground. Remarkably, few deaths were ever recorded, though the poorest among the dead were never carefully counted. London was still there, its name, its river, its people, but the city we had just walked through was not. What rose from the ashes was, in one sense, a triumph. London refused to die. Within a single generation, it had not only recovered, but soared past half a million people, overtaking Paris to become the greatest city in all of Western Europe. There were dreams of building it anew, grand designs with sweeping avenues and open squares, drawn up by men like Christopher Wren. They were all set aside. It was simpler and far quicker to rebuild upon the very same tangled streets as before. But this time, a new law forbade the old timber. The city would rise again in brick and stone. And in the years that followed, on the hill where the broken Gothic giant had stood, Wren raised the great dome of a new St. Paul's, the one that watches over the river still. And so London came back. But understand what that truly means. The London that came back was not the London that had burned. You cannot rebuild a thousand-year-old labyrinth or reopen a marketplace inside a cathedral. You cannot raise again the wooden ring where so many of Shakespeare's words first rang out, or restore a city that had grown like a living thing, inward and upward, lane folding into lane. That London was not repaired. It was replaced by a cleaner, grander, safer city built upon its grave. Of the original, almost nothing survives. A handful of engravings, a few blackened relics, and the pages of two men who walked its streets and watched them burn, Samuel Pepys and John Evelyn. We have been able to walk through it at all tonight only because they troubled to write it down. The London of stone you can visit today is real, but beneath its feet lies an older one, a city of timber and tar that stood for a thousand years and was gone in four days. And almost everyone who walks those streets now has long forgotten it was ever there at all. Subscribe to the channel and let's keep reviving the past together. See you on the next journey.
