Best Things to Do in Valencia, Spain: Hidden History, Architecture & Local Secrets

Most travel guides to Valencia begin at the beach or the paella pan. The more interesting story starts underground. The Roman colony of Valentia Edetanorum was founded in 138 BC by the consul Decimus Junius Brutus, making it one of the earliest Roman settlements on the Iberian Peninsula. Today, beneath the Plaza de la Virgen, the Almoina Archaeological Centre exposes a literal cross-section of urban time: Roman forum pavements, a Visigothic episcopal complex, and Moorish hammam baths physically stacked on top of each other in the same excavation pit. You walk a glass-floored walkway above 2,000 years of continuous civilisation.

The Moorish chapter, which began with the conquest of 711 AD, left a mark that still shapes everyday Valencian life. The acequia network — an intricate system of irrigation canals feeding the rice fields and orchards of the Valencian plain — was engineered during the Islamic period and remains operational today, still governing eight main channels that distribute water across the huerta. The body that oversees them, the Tribunal de les Aigües, has met every Thursday since the 10th century at the Cathedral's Puerta de los Apóstoles. Proceedings are entirely oral — no lawyers, no written records, no appeals. Sentences are final and delivered in Valencian. It holds the distinction of being the world's oldest continuously functioning court of justice, recognised by UNESCO.

The Barrio del Carmen, Valencia's oldest neighbourhood, preserves two of the city's medieval gates: the Torres de Serranos (1392) and the Torres de Quart (1444), both built when Valencia was the wealthiest city on the Iberian Peninsula. To understand how all these layers connect, the Kickstart Valencia private tour is designed precisely for first-time visitors who want context before sightseeing, while the Highlights & Secrets of Valencia tour goes deeper into the Roman and Moorish legacy with a local guide who knows where the trapdoors are.

Stand inside La Lonja de la Seda — the Silk Exchange, built between 1482 and 1548 — and look up. The Sala de Contratación is held aloft by 24 twisted helical columns, each 17.4 metres tall, designed deliberately to resemble a forest of stone trees. The intention was psychological: merchants conducting business beneath them were meant to feel the weight of nature's grandeur and, by implication, God's watchfulness. A Latin inscription running along the cornice warns explicitly against fraud. The building is a UNESCO World Heritage Site and one of the finest examples of Valencian Gothic civil architecture in existence — arguably more impressive than many of Spain's cathedrals.

Ten minutes by bike to the south, the city snaps five centuries forward. Santiago Calatrava's Ciudad de las Artes y las Ciencias, completed between 1998 and 2005, is Valencia's most polarising and most photographed achievement. The Hemisfèric mimics a giant human eye — eyelid, iris, pupil — reflected in a shallow pool. The Palau de les Arts Reina Sofía is clad in trencadís mosaic, the broken-tile technique Calatrava inherited directly from Gaudí. The Umbracle, an open-air garden walkway, echoes the Lonja's columns through its curved concrete ribs — an architectural conversation across five centuries that is almost certainly intentional.

Between these two poles sits Valencia's Cathedral — itself an architectural argument, with a Romanesque portal, a Gothic nave, and a Baroque façade — and a claim that its Capilla del Santo Cáliz houses the Holy Grail: a 1st-century AD agate cup documented in Vatican records since the 3rd century. The Highlights & Secrets of Valencia tour covers the Cathedral's hybrid identity in detail. For the Calatrava complex and the Turia Gardens connecting them, the Valencia Private Bike Tour is the most elegant way to bridge the gap, while the Full Day Highlights, Museums & Paella tour takes in the major architectural landmarks alongside a proper paella lunch.

Paella was not invented in a restaurant. It originated in the rice-farming villages bordering the Albufera lagoon in the 18th century, cooked outdoors by agricultural workers over fires of orange wood. The authentic paella valenciana — rabbit, chicken, ferradura green beans, garrofó butter beans, and rice — is protected by the Comunitat Valenciana with an official recipe. The rice itself matters: the lagoon's Denominació d'Origen-certified senia and bomba varieties, grown in paddies that have been flooded since Moorish times, absorb stock differently from any other grain and produce the characteristic socarrat crust at the base of the pan. To taste it in its proper context, the Albufera Day Trip takes you to the lagoon itself at golden hour.

For an immersion in Valencia's market culture, the Mercado Central — opened in 1928, covering 8,000 square metres under a Modernista iron-and-tile dome — is one of Europe's largest covered food markets. Here you can try horchata de chufa, a cold milky drink made from tiger nuts with Moorish roots, alongside the elongated sugar-dusted fartons pastries made for dipping. The Food & Drinks Valencia private tour navigates the market with a guide who knows the vendors worth talking to.

Then there is fire. The Fallas festival — listed as UNESCO Intangible Cultural Heritage in 2016 — fills Valencia every March with over 800 satirical giant sculptures (ninots), constructed over an entire year and incinerated on the night of March 19th, the feast of Saint Joseph. The Nit del Foc and the daily mascletà explosions in the Plaza del Ayuntamiento are measured not in decibels of sound but in percussion — felt in the chest as much as heard. The Museo Fallero preserves the single ninot voted to be pardoned from the flames each year, a record that now stretches back decades.
