Transcript
- Lucas: So, we've talked about Roman roads and aqueducts, but there's another massive Roman construction project that often gets overshadowed — the frontier walls. And the most famous one, of course, is Hadrian's Wall across northern England. Luna: I've seen pictures — it's this snaking stone wall across rolling green hills. But why was it built, exactly? Was it just to keep the Scots out? Lucas: That's the popular image, but it's more nuanced. Hadrian visited Britain in 122 CE, a few years into his reign. He was consolidating the empire's borders after his predecessor Trajan's overexpansion. The Historia Augusta says he was the first to build a wall 80 miles long to separate the Romans from the barbarians. But it wasn't just a barrier — it was a controlled frontier for trade, customs, and movement. Luna: So it was more like a border checkpoint than a fortress wall. Lucas: Exactly. And it's incredible that so much of it survives. The wall runs from the River Tyne near Newcastle in the east to the Solway Firth in the west. It was about 15 feet high in places, with a ditch in front and a massive earthwork called the Vallum behind it. Every Roman mile there was a milecastle — a small fort with a gate — and between each milecastle were two turrets, so the entire wall was constantly watched. Lucas: The wall was built by soldiers from three legions: the Second Augusta, the Sixth Victrix, and the Twentieth Valeria Victrix. They were assisted by auxiliaries and local labour. It took about six years to complete. And it wasn't all stone — the western section was originally turf on a stone base, probably because stone was harder to come by there. Luna: Wait, so the legions themselves did the construction? I thought they just fought. Lucas: Roman legionaries were master builders. They built roads, bridges, aqueducts, and walls. In fact, many soldiers spent more time building than fighting. And the wall was a huge engineering project. They had to quarry stone, shape it, transport it, and then build to precise specifications. The milecastles, for instance, varied in design but were all roughly 60 feet square. Lucas: Speaking of building — and this might seem like a tangent, but it ties in — if you've been enjoying our deep dives into ancient engineering and history like this, you might appreciate that this show is ad-free and listener-supported. It's just me and Luna having these conversations, and we can keep going deep into topics like Hadrian's Wall because of listeners who chip in at buy me a coffee dot com slash fexingo. It's a small way to say 'keep exploring' — and it really helps. Luna: Yeah, it's like being a patron of the old Roman builders — you make it possible for us to keep digging. Lucas: Exactly. So, back to the wall. There were also major forts built into or just behind the wall, like Vindolanda and Housesteads. These housed the garrison troops — auxiliaries from all over the empire. We've found writing tablets at Vindolanda that give a vivid picture of daily life: soldiers complaining about supplies, invitations to birthday parties, even a request for more socks. Luna: Socks? In Roman Britain? That's surprisingly relatable. Lucas: Right? The Vindolanda tablets are one of the most important archaeological finds in Britain. They're thin wooden leaves with ink writing, preserved in the anaerobic conditions of the fort's rubbish pits. They mention everything from beer rations to a soldier named Masclus asking for more beer. It humanises the frontier. Lucas: But the wall wasn't the only frontier. Twenty years later, under Antoninus Pius, the Romans pushed north and built another wall — the Antonine Wall — across the narrowest part of Scotland, between the Firth of Forth and the Firth of Clyde. That one was turf on a stone base, and shorter — about 37 miles. But it was only occupied for about 20 years before they pulled back to Hadrian's Wall. Luna: So the Antonine Wall was like a failed experiment in overreach? Lucas: Partly. The tribes in what's now Scotland — the Caledonians — were fiercely resistant. The terrain was harsh, and supplying the northern wall was logistically difficult. So Hadrian's Wall became the permanent frontier for most of the rest of Roman rule in Britain, until the early 5th century. Lucas: The wall also had a civilian side. Settlements grew up around the forts, called vici. There were merchants, craftsmen, families. At places like Arbeia in South Shields, we've found evidence of a multicultural community — soldiers from Spain, Syria, and North Africa. The frontier was a melting pot. Luna: So it wasn't just a wall in the middle of nowhere — it was a bustling zone. Lucas: Absolutely. And the wall itself changed over time. Gates were narrowed or blocked, towers were added, and after the Romans left, locals reused the stone for churches and farmhouses. In the 19th century, antiquarians like John Collingwood Bruce began studying and preserving it, and now it's a UNESCO World Heritage site. Luna: I've always wanted to walk the Hadrian's Wall Path. Is it the whole 80 miles? Lucas: It is — 84 miles from Wallsend to Bowness-on-Solway. You can see the best-preserved sections in the middle, around Housesteads and Vindolanda. The landscape itself is stunning, especially in the summer. And you get a real sense of what it meant to live on the edge of the Roman world. Lucas: One more thing: the wall wasn't just defensive. It was a statement of Roman power. Hadrian was consolidating the empire after his predecessor's wars, and he wanted to show that Rome could define and control its boundaries. The wall said: this is where civilisation ends, and beyond lies barbaricum. Luna: It's almost like a line drawn in the earth saying 'so far, and no further'. Lucas: Exactly. And it worked for nearly 300 years. The wall was garrisoned, maintained, and adapted. It's a testament to Roman engineering — and to the limits of empire. In the end, the wall didn't stop the barbarians, but it defined a frontier that shaped Britain for centuries. Luna: Thanks, Lucas. I think I need to plan that walk now. Lucas: Do it. And when you're standing on the wall, looking north, you'll understand why it's one of the most evocative remnants of the Roman Empire.
