Latest / Nero: Mad Tyrant or Misunderstood Emperor? — Fexingo History / Nero's Urban Renewal: Rebuilding Rome After the Great Fire
Transcript
- Lucas: So, Luna, we've talked a lot about the Great Fire of Rome in 64 AD — how it destroyed ten of the fourteen districts, left hundreds of thousands homeless, and raised all those suspicions about Nero. But what I've always found fascinating is what happened next, because Nero took the destruction as a chance to rebuild the city from scratch in a way that was almost modern. Luna: I thought he just built his Golden House over the ruins. Lucas: That's the popular image, but there was a lot more to it. The Domus Aurea was only part of his plan — the palace and its massive parkland took up about a quarter of the burned area. But before that, he issued a new set of building regulations that completely changed how Rome was constructed. Narrow, winding streets were out; wide, straight avenues with porticoes were in. Buildings had to be made with fireproof materials — mostly concrete and brick instead of wood — and they couldn't exceed a certain height, around seventy feet, to prevent them from collapsing onto the streets. Luna: So he was actually trying to prevent another fire? That sounds responsible, not tyrannical. Lucas: Exactly. Tacitus — who's no fan of Nero — actually gives him credit for these measures. He writes that Nero offered rewards for builders who used stone and concrete, and he even paid for the debris to be removed from the Tiber at public expense. The new insulae, or apartment blocks, were required to have individual courtyards and no shared walls, which helped stop fires from spreading. He also mandated that all houses have a portico in front — a covered walkway — so that if a fire did break out, people could escape along them and firefighters could access the buildings easily. Luna: Wait, Tacitus praised Nero? I thought he was one of his harshest critics. Lucas: He is, but even Tacitus admits the rebuilding was well-conceived. He says, and I'm paraphrasing, that the new city was safer and more beautiful than before. Nero also sponsored the construction of public buildings — the Baths of Nero near the Pantheon, the Macellum Magnum, which was a giant market hall on the Caelian Hill, and the Neronian Forum, which was a new forum with a temple and a massive colonnade. He even started work on a canal from Lake Avernus to the Tiber, but that never finished. Luna: So he was kind of an urban planner? But didn't he also raise taxes to pay for all this, and didn't a lot of people get displaced? Lucas: That's the other side of the coin. To fund the rebuilding, Nero introduced new taxes and forced contributions from the provinces. He also confiscated land for the Domus Aurea from wealthy families, which made him enemies. And yes, the poor who had lived in the crowded wooden tenements were pushed out to the suburbs. The new insulae were better built, but they were more expensive to rent, so many people ended up on the edges of the city. Suetonius says Nero also offered grain handouts to win back the populace, but the overall effect was that the fire did to Rome what a systematic urban renewal program might have done — but with a lot of pain along the way. Luna: So he used the disaster to reshape the city in his own image, literally, with the Colossus and the Golden House. Lucas: Yes, and that's what the historians focus on. The Domus Aurea was an enormous palace and park that included vineyards, artificial lakes, and a colossal statue of Nero as the sun god, Sol Invictus. It was so extravagant that later emperors, especially Vespasian and Trajan, built over it — the Colosseum was built on the site of the artificial lake. But the building codes and the new civic infrastructure actually survived Nero's fall and influenced Roman architecture for generations. His successors kept the height restrictions and the use of fireproof materials, even as they erased his name from the monuments. Luna: So he left a positive legacy in urban planning even though his reputation was trashed. That's ironic. Lucas: Exactly. And it's one of those moments in history where the sources — Tacitus, Suetonius, Cassius Dio — give us a mixed picture. They all report the building codes, but they frame them as Nero's attempt to buy popularity or as part of his megalomania. But if you look at the actual measures, they were pragmatic and forward-thinking. For instance, he also regulated how buildings could be constructed near the Tiber, to prevent future floods. He even considered using the rubble to build an embankment wall, though that was only partially done. Luna: What about the fire itself? Did the rebuilding make people suspicious that he started it? Because he benefited from all this space. Lucas: That's the classic argument against him. Cassius Dio says Nero wanted to build a new city and so he set the fire. Suetonius even claims he sang about the fall of Troy while watching the flames. But most modern historians doubt that, because the fire started in the Circus Maximus, near the wooden shops, and it spread uncontrollably. Nero wasn't in Rome at the time — he was in Antium, about thirty-five miles away. He rushed back and opened his palaces to the homeless. But the fact that he then took so much land for his own palace fueled the conspiracy theories. It didn't help that he built a huge golden house right in the middle of the burned area. So the same act — rebuilding — could be seen either as benevolence or as self-serving opportunism. Luna: So it's all about perspective. I guess we're still arguing about that two thousand years later. Lucas: We are. And the rebuilding of Rome after the fire is a perfect lens for that debate. It shows Nero as both a visionary and a tyrant. He made the city safer and more beautiful, but he didn't do it for the people — or at least, not only for them. He did it to leave his mark on the eternal city. And in the end, most of his physical mark was erased. The Domus Aurea was filled in, the Colossus was recast as the sun god, and his name was chiseled off public buildings. But his building regulations stayed, and they shaped Rome for centuries. Luna: It reminds me of what we said about Trajan's building projects — but Trajan got the credit, while Nero got the blame. Lucas: Exactly. And that brings us to something else: the cost of all this. The rebuilding put a huge strain on the imperial treasury, which was already struggling because of Nero's earlier debasement of the coinage — we talked about that in episode 182. He had to squeeze the provinces harder, and that created resentment. In Britain, the aftermath of Boudicca's revolt left the province in ruins, and in Gaul, the heavy taxes contributed to Vindex's rebellion in 68 AD. So the urban renewal of Rome, as well-intentioned as it was, helped set the stage for Nero's downfall. He spent money he didn't have, and when the provinces revolted, his support evaporated. Luna: So the same building projects that should have been his legacy also helped bring him down. It's like a Greek tragedy, really. Lucas: It is. And you know, it's interesting how history remembers him. We tend to focus on the fire, the persecution of Christians, the murder of his mother, and the debauchery. But the practical side — the building codes, the public baths, the market hall, the forum — those are often forgotten. Yet they directly affected the daily lives of hundreds of thousands of Romans. They walked on his streets, bathed in his baths, shopped in his market. And they didn't care who built them, as long as they worked. Luna: I don't know; if I were a Roman, I think I'd care a little. But you're right that the physical legacy outlasts the moral one. It makes me wonder what future historians will say about our own city planning. Lucas: That's a great point, and it's one of the reasons I love talking about this. History is never just about one person — it's about how that person's actions ripple through time. And for all his faults, Nero's Rome was a city that was safer, more organized, and more magnificent than the one that burned. Even his harshest critics had to admit that. Luna: So do we have any physical evidence of these codes? Like, can archaeologists see the difference in the buildings from before and after the fire? Lucas: We can. The insulae that were built after the fire — like the ones at the foot of the Capitoline Hill — show the new rules: thick concrete walls, brick-faced facades, and no wooden supports. The famous Insula of the Ara Coeli is a later example, but it follows the same principles. Also, the Baths of Nero, though much rebuilt, still show the scale of his ambition. And the Macellum Magnum appears on the Severan Marble Plan, though only fragments survive. So yes, the archaeological record confirms what the texts say. Luna: You know, we've been talking about how Nero used the fire to remake Rome. And in a way, this podcast is our own remake of history — we're rebuilding Nero's reputation brick by brick, conversation by conversation. And it's only possible because listeners like you make it ad-free and independent. Lucas: Luna, I love that connection.

Every little bit helps us keep the research going and the episodes ad-free. Luna: Yeah, it's like our own building fund. So, speaking of building, after the fire, Nero also had to deal with the grain supply, right? Because the fire destroyed the warehouses near the Tiber. Lucas: Exactly. That's a crucial point. The fire had wiped out the main grain storage facilities, and there was a real risk of famine. Nero actually took emergency measures — he ordered grain from Ostia and the provinces to be shipped directly to the city and distributed at reduced prices. He also used the imperial granaries to stabilize the market. Tacitus notes that Nero even sent ships to Egypt and Africa to speed up deliveries. So again, a practical response to a crisis, not just building monuments. Luna: But didn't that cost a fortune too? And eventually the grain dole had to be cut? Lucas: It did. The financial strain was immense. And one of the results was that Nero began confiscating property from wealthy senators and equites to pay for things. That made him more enemies, especially among the elite. So the rebuilding of Rome, while it benefited the plebs in the short term, alienated the very people who could have supported him in a crisis. It's a pattern we see throughout his reign — he tries to do something popular, but the way he does it creates backlash. Luna: I think that's the real tragedy of Nero. He had good ideas, but he had no idea how to implement them without stepping on toes. Lucas: That sums it up beautifully. And it's why studying Nero isn't just about a mad emperor or a misunderstood one — it's about the complexity of power. One person can have a vision, but if they don't carry the right people with them, that vision gets buried under the rubble of their own mistakes. Luna: So with that in mind, what do you think Nero's most important architectural contribution was? Was it the Domus Aurea or the building codes? Lucas: I'd say the building codes, because they had a longer impact. The Domus Aurea was ephemeral — it was stripped and built over within a few decades. But the building regulations influenced Roman architecture for centuries. They were incorporated into later building manuals, and the use of concrete and brick became standard. Trajan's Markets, the Baths of Caracalla, even the Basilica of Maxentius all owe something to Nero's post-fire reforms. He didn't invent concrete, but he mandated its use in ways that changed the city's skyline. Luna: That's a legacy he probably wouldn't have predicted. But then again, Nero was an artist — maybe he'd be proud that his aesthetic choices outlasted his political ones. Lucas: He might. And that's a fitting note to end on. Nero's Rome was built on ashes, literally and figuratively. It rose again — safer, grander, but also more divided. And that tension is what makes his story so compelling.
