Latest / Nero: Mad Tyrant or Misunderstood Emperor? — Fexingo History / Nero's Building Boom: Urban Renewal After the Fire
Transcript
- Lucas: So we've talked a lot about the Great Fire of 64 AD in previous episodes — the damage, the scapegoating of Christians, Nero's infamous cithara performance during the blaze. But what we haven't really dug into is what happened after the fire went out. Luna: The rebuilding, you mean? I always assumed it was just a mess for years. Lucas: Actually, Nero moved surprisingly fast. Within months, he had a comprehensive urban renewal plan in place. And it's one of the most fascinating — and controversial — aspects of his reign. The fire destroyed about 70% of the city, according to Tacitus. Ten of fourteen districts were devastated. That's hundreds of thousands of people suddenly homeless. Luna: So where did they all go? Lucas: Nero opened the Campus Martius, the Saepta Julia, even his own gardens and the Domus Transitoria — his earlier palace — to shelter the refugees. He also waived harbour dues on grain shipments and reduced the price of corn. But the real challenge was what to do with the city itself. The old Rome was a labyrinth of narrow, winding streets, with overcrowded insulae — those multi-storey apartment blocks — built of timber and mud brick, with no fire safety whatsoever. Lucas: So Nero, in collaboration with his architects Severus and Celer — the same ones behind the Domus Aurea — designed a new building code, the lex de modo aedificiorum. It's a remarkable piece of urban planning. Luna: What did it actually say? Lucas: First, streets were to be widened and laid out in straight lines, not the old crooked alleys. Second, building heights were capped — no more than 70 feet, roughly seven storeys. And third, every new structure had to have a portico, a covered colonnade, along the street front. These porticoes were built of stone or concrete, with flat roofs that could be used by firefighters to access upper floors. Nero even offered cash incentives for builders who used fire-resistant stone and concrete instead of timber. Luna: So he was basically mandating fire safety codes. That sounds almost modern. Lucas: Exactly. He also reformed the vigiles, the fire brigade. The praefectus vigilum was given more authority and funding. Public water points were increased, and each house was required to have its own water supply. Tacitus says — and I'm paraphrasing — 'the new city was less beautiful, but healthier and safer'. Luna: Wait, 'less beautiful'? Why would a porticoed street be uglier? Lucas: Tacitus was a traditionalist. He preferred the old haphazard charm. But archaeological evidence shows that the new streets were impressive — wide, straight, lined with uniform porticoes. It was a Hellenistic style, inspired by the great cities of the Greek East like Antioch and Alexandria. Nero was consciously trying to modernize Rome, to make it a world capital worthy of an empire. Lucas: But here's the rub: to do all this, Nero needed land. And that meant seizing property, often without full compensation. He declared that any debris from the fire could be cleared at public expense, but then he took possession of the cleared lots. Suetonius claims he forced owners to sell at a loss, and that the new streets were designed to give him easier access to his own Domus Aurea. Luna: And that's where the resentment built up. Lucas: Absolutely. The urban renewal was efficient, but it was also autocratic. The rich lost their prime real estate; the poor were pushed to the outskirts. The Domus Aurea itself, that sprawling palace complex, took up a huge chunk of the city centre — land that could have housed thousands. So while Nero could claim he was rebuilding Rome as a safer, more beautiful city, his critics saw a land grab. And that's a big part of why he was so hated by the senatorial class. Luna: So was the building code actually enforced? Or did it fall apart after Nero died? Lucas: It's a mixed legacy. The porticoes and wider streets certainly survived — you can see traces of the new street grid in the Roman Forum area today. The height limit might have lapsed, because later insulae in other parts of the empire were taller. But the concept of building codes stuck around. And ironically, one of the most enduring symbols of Nero's building program is the Colosseum — built by Vespasian on the site of the Domus Aurea's artificial lake. The lake itself was part of Nero's grand design, but the amphitheatre that replaced it is a direct repurposing of his urban vision. Luna: So Nero's building boom shaped Rome for centuries, even if people didn't want to credit him. Lucas: Exactly. The Flavian emperors, who succeeded him, continued many of his urban policies. They just erased his name. But the evidence is still there in the concrete and stone. And when you look at the sheer speed of the reconstruction — much of the city was rebuilt within a decade — you have to admire the organisational effort. It wasn't just propaganda; it was a real attempt to solve a real crisis. Whether you see it as enlightened reform or tyrannical overreach probably depends on whether you owned land on the Palatine. Luna: Or whether you were one of those displaced families. Lucas: Right. And that's the tension that runs through so much of Nero's rule. He had big ideas, but he trampled on people to achieve them. The new Rome was safer, but it was also his Rome. And that's something to think about the next time you walk through a city with wide boulevards and uniform building lines — the legacy of an emperor who wanted to be remembered as a creator, but ended up as a cautionary tale.
