In 138 BC, Roman legionaries drove stakes into the fertile plain between two tributaries of the Turia river and declared a new colony: Valentia Edetanorum. Nearly 2,200 years later, you can still walk the exact line of their main road — now called Calle Caballeros — without realising that every step follows a Roman surveyor's chalk mark. Valencia's old town is one of Europe's most layered urban spaces: a Roman grid absorbed by a Moorish medina, recaptured by a Christian king, gilded during a 15th-century mercantile golden age, left to crumble, and then spectacularly reinvented by artists and night owls in the 1980s and 90s. The result is a neighbourhood — the Barrio del Carmen — where a Gothic palace shares a wall with a street-art mural, and where the oldest functioning court in Europe convenes on the pavement every Thursday at noon. This guide walks you through it all, street by street, stone by stone.
Valencia Was Founded by Rome — and Its Old Town Still Follows the Ancient Grid
The Roman consul Decimus Junius Brutus founded Valentia Edetanorum in 138 BC as a settlement for veterans of the Iberian Wars — making Valencia one of the oldest Roman cities on the Iberian Peninsula. The city was laid out on the standard Roman grid: a Decumanus Maximus running east to west, and a Cardo Maximus cutting north to south at right angles. Walk Calle Caballeros today and you are walking the Decumanus Maximus. The street's alignment, width, and relationship to the Cathedral square are not medieval accidents — they are Roman engineering that every subsequent civilisation simply chose to keep.
The layers beneath that pavement are extraordinary. At the Almoina Archaeological Centre, a glass-floored museum built directly over the excavations, you can look down into the Roman forum, the remains of a 4th-century paleo-Christian basilica, and the thermal baths that served the colony for centuries. The site sits steps from La Catedral de Valencia — itself built over a Visigothic church, which was built over a mosque, which was built over the Roman temple. History in Valencia is not behind glass; it is underfoot.
After Rome came the Visigoths, and then, in 711 AD, the Moors — who renamed the city Balansiya and ruled for over five centuries. In 1238, King Jaume I of Aragon led the Christian reconquest and Valencia became the capital of a new kingdom. The city's medieval walls — of which two magnificent gates survive — were raised and expanded during this era. The Torres de Serranos, built between 1392 and 1398, guard the northern entrance; the Torres de Quart, added in the 15th century, command the west. Walking through either gate is the clearest threshold experience the old town offers: you pass from the modern city into a space still shaped by the 13th century. Both towers and the Almoina are core stops on the Highlights & Secrets of Valencia tour, and feature prominently on the Kickstart Valencia half-day itinerary for first-time visitors.
The Barrio del Carmen: Gothic Palaces, Bohemian Lanes, and a Neighbourhood That Reinvented Itself
The Barrio del Carmen is Valencia's oldest inhabited neighbourhood and the densest concentration of medieval architecture in the city. Its boundaries are essentially those of the Roman colony — and within them, the streets are so narrow that upstairs neighbours could theoretically shake hands across the gap. This is where Valencia's story is most legible, written in stone across eight centuries of construction and reinvention.
Start with the Palau de la Generalitat Valenciana, a Gothic-Renaissance palace whose construction began in 1421 and which remains — remarkably — the seat of the regional government today. Two blocks south, the Lonja de la Seda (Silk Exchange) stands as one of the finest examples of secular Gothic architecture in Europe, awarded UNESCO World Heritage status in 1996. Its Sala de Contratación — the trading hall — features spiralling columns 17.4 metres tall that twist like braided rope, supporting vaulted ceilings without a single cross-rib: an engineering feat that astonished the 15th century.
Calle Caballeros itself tells the social history of the era. During Valencia's 15th-century Golden Age — when the city was the most important commercial hub in the western Mediterranean — this was the address of choice for the city's noble families. Merchants who grew rich on the silk trade built their palaces here, and the street hummed with the politics and pageantry of a city at its peak. That Golden Age produced the Lonja, the Cathedral's Miguelete tower, and much of what makes the old town visually extraordinary today.
Directly across from the Lonja, the Mercado Central — opened in 1928 — covers 8,000 m² under a soaring Art Nouveau structure of iron, tile, and stained glass, making it one of the largest fresh produce markets in Europe. Nearby, the Plaça de la Virgen — Valencia's ancient Roman forum — remains the sacred and civic heart of the city, framed by the Cathedral, the Basílica de la Virgen de los Desamparados, and the Palau de la Generalitat. And for those willing to wander a few minutes off the main drag: the Plaça del Tossal, built over the site of a Moorish gate, is a quiet, photogenic square that the vast majority of visitors never find. The Architectural Tour Valencia and the Highlights & Secrets of Valencia tour both dig into this neighbourhood's layers with a local guide who knows which doorways to stop at — and why.
What First-Time Walkers Always Miss: Sensory Stops, Local Rhythms, and the Right Time of Day
The old town belongs to different cities depending on what time you arrive. Between 7 and 9am, it runs on a local timetable: market delivery vans idle in alleys, bakeries exhale warm air onto cool streets, and the Mercado Central receives its produce with the efficiency of a well-rehearsed performance. There are no tour groups. This is Valencia as Valencians experience it. By midday, the squares are busy and the light is flat. The best photographic window — and the finest moment to be standing beneath the Cathedral's Miguelete tower — is the post-siesta golden hour, when low light wraps the octagonal bell tower (built 1381–1424, 207 steps) in a warm amber glow that no filter can replicate.
For a food walk, the Mercado Central is the obvious anchor — but pair it with the Mercado de Colón (1916, Modernista architecture, now a gourmet food hall in the Eixample district) for a study in contrast: one is raw, loud, and gloriously chaotic; the other is curated and calm. The Food & Drinks Valencia tour covers both with a guide who knows the stallholders by name.
Make the Horchatería de Santa Catalina — operating continuously since 1836, tucked beside the Gothic church of the same name — your first stop of the day. Horchata de chufa (tiger nut milk, chilled) and fartons (a long, glazed bread for dipping) consumed before 11am, before the tour buses arrive, is the Valencian ritual every visitor should complete at least once.
At noon every Thursday, the Tribunal de les Aigües (Water Tribunal) convenes at the Cathedral door: eight elected judges, representing the eight ancient irrigation channels of the Turia plain, hear disputes in Valencian dialect and deliver oral judgements on the spot. The tradition has run unbroken since the 10th century and was inscribed on UNESCO's Intangible Cultural Heritage list in 2009 — making it the oldest functioning court in Europe. It lasts about 15 minutes and costs nothing. Finally, walk the edge of the old town where the city's river used to run. After catastrophic flooding in 1957, the Turia was diverted south of the city and its 9km riverbed was transformed into the Jardín del Turia — a green corridor where locals run, cycle, and play football, largely invisible to itinerary-driven tourists. The Valencia Bike Tour follows this corridor beautifully, and the Full Day Valencia tour weaves the park into a complete city narrative.
Explore Valencia's Old Town With a Local Guide
The old town's richness is precisely what makes it easy to walk past. Without knowing that the pavement beneath Calle Caballeros follows a Roman road, or that the spiralling columns of the Lonja were considered structurally impossible in their time, or that the court convening at the Cathedral door on Thursday has been doing so for over a thousand years — it's just a pretty neighbourhood. A good guide turns the stones into stories.
Several Local Cool Tour experiences start or pass directly through the Barrio del Carmen and the Cathedral quarter, covering the streets, squares, and stops described in this guide:
