Cartagena
"In Cartagena you don't visit ruins — you walk on top of them, unaware, until someone points at your feet."
Three thousand years of empires stacked into one Mediterranean port — Carthaginian, Roman, Byzantine, and modern Spanish navy, all visible if you know where to dig.
The first thing that unsettled me about Cartagena was learning that the shopping street I’d walked down twice, coffee in hand, sat directly above a Roman theatre that nobody knew existed until 1988, when construction workers building a cultural center hit marble seating instead of soil. That’s Cartagena in miniature: a city so continuously inhabited for so long that its own history kept getting paved over by the next layer, and the next, until archaeologists had to peel the town back like an onion to find what was underneath.
A City Carthage Built, Rome Perfected
Cartagena’s name is a corruption of Carthago Nova — New Carthage — founded around 227 BC by Hasdrubal the Fair as the Carthaginian capital in Iberia, the launching point from which Hannibal set out on the campaign that would eventually cross the Alps with elephants. Rome took the city in 209 BC during the Second Punic War and made it one of Hispania’s wealthiest ports, largely on the back of the silver and lead mines in the surrounding sierras. The Teatro Romano, that theatre beneath the shopping street, was built around 5 BC under Augustus and could seat six thousand people; today it’s the centerpiece of a museum designed by Rafael Moneo that lets you descend through medieval fish-salting works and a Moorish-era neighborhood before reaching the Roman stone itself, layer by literal layer.
The Castle, the Harbor, and the Navy That Never Left
Above it all sits the Castillo de la Concepción, a hilltop fortress with roots in the Byzantine period — Cartagena was briefly the capital of Byzantine Spania in the sixth century, a fact most visitors never learn because so little of that era survives above ground. From the castle’s terrace the harbor spreads out in a near-perfect natural bowl, which is exactly why Carthaginians, Romans, and later the Spanish Bourbon navy all chose this spot. Cartagena has been a major naval base since the eighteenth century, and modern warships still dock in the same protected waters that sheltered Hasdrubal’s fleet. I stood at the mirador at dusk watching a grey navy vessel slide past a two-thousand-year-old shoreline and couldn’t decide which felt more improbable.
Down in the old town, Modernist facades from the city’s late-nineteenth-century mining boom line Calle Mayor — Cartagena had its own art nouveau flourishing, funded by lead and silver money, distinct from and less visited than Barcelona’s. I ducked into a bar for a plate of michirones, the dried fava bean stew that’s Cartagena’s own contribution to Spanish comfort food, thick and paprika-dark and utterly unphotogenic. It was one of the best things I ate in the whole region.
When to go: Late September during Carthaginians and Romans Festival turns the whole city into a costumed reenactment of its founding conflict; for calmer visits, May and early June give warm days without the summer cruise-ship crowds.
