Valencia has completely won me over the past few seasons — what used to be a "sleepy" port is now one of the hottest calls in the western Mediterranean, averaging 4.7–4.9 stars across cruise reviews. But here's what the ratings can't capture: this is a city founded in 138 BC by Roman consul Decimus Junius Brutus Callaicus as "Valentia Edetanorum" — "Valentia" meaning "strength" or "valour" — to honor veteran soldiers who'd fought across Hispania. That ancient strength still pulses through the streets, even as the city races confidently toward the future.

My perfect day begins with a 10-minute tram ride from the ship straight to Santiago Calatrava's jaw-dropping City of Arts and Sciences — and yes, Calatrava is a native son, born right here in Valencia. His futuristic whale-skeleton buildings seem to rise from another century entirely, yet they rest on land that once knew Pompey's fury (he razed the city to the ground in 75 BC), Muslim scholars (who ruled from 714 as "Balansiya"), and the triumphant armies of Aragon (who reclaimed it for Christendom in 1238). The Oceanogràfic — Europe's largest aquarium — offers a shark tunnel and dolphin show that never fail to take my breath away.

Then I rented a bike and rode the 9 km of gardens along the old Turia riverbed — the very river that flooded catastrophically in 1957, prompting the city to divert it and transform the dry channel into this linear park that now connects past and future. I pedalled into the historic center for the Central Market, where fresh-squeezed orange juice and oysters opened at the counter made me forget what time zone I was in, then on to La Lonja de la Seda — the Silk Exchange, built between 1482 and 1533, a UNESCO World Heritage site since 1996. Standing beneath those soaring Gothic columns, I was reminded that Valencia financed Columbus's 1492 voyage during its 15th-century Golden Age, when Valencian merchants commanded trade routes across the known world.

I stopped my bike halfway back through the Turia gardens, near a cluster of orange trees whose blossoms filled the air with a sweetness so thick I could taste it. Children were climbing on a giant Gulliver sculpture while their parents sat on benches in the shade. A woman was reading alone, her shoes kicked off, bare feet on the warm stone. The gardens buzzed with ordinary happiness — the kind that only exists in a place people have decided to love. I parked the bike and sat on a wall, drinking water from a bottle that had gone warm in the sun, and thought about what this riverbed used to be.

In 1957, the Turia river flooded and killed eighty-one people. The water rose to five metres in parts of the old town. There are plaques on buildings marking where it reached. The city's response was not to rebuild what was there — they diverted the river entirely and turned its empty bed into nine kilometres of gardens, playgrounds, fountains, and footpaths. I sat there in what used to be a disaster and felt my eyes fill with tears I had not expected. My mother had died three months before this trip. I had booked the cruise because I needed to be somewhere that was not our house, somewhere that did not smell like her perfume or echo with her absence. And here, in a garden planted where a flood had killed people, I understood something I had been refusing to learn: that the worst thing that happens to you does not have to be the last thing that defines the place. The riverbed was proof. The city had grieved, and then it planted trees.

Looking back, Valencia taught me that strength — valentia — is not what I expected. It is not the Roman soldiers who named the city or the armies who fought over it for two thousand years. It is the decision to make something good from something ruined. A riverbed becomes a garden. A sleepy port becomes a city people come back to. A grieving son gets on a bicycle and rides nine kilometres through orange blossoms and realises, for the first time in months, that he is going to be all right. The ancient strength of this city is not in its walls. It is in what it chose to grow.
