Starting near Xàtiva station, opposite the bullring, you'll open the Explorial app, enter the 6-digit game code that you received by text and Viator chat message, and head into the monumental quarter. The tour is fully self-guided — no guide, no fixed start time, just your group and the city. El Mercado Central sets the tone: one of Europe's oldest running food markets under a dome of iron and stained glass. Riddles trade in oranges, eels and modernista details. Across the street, La Lonja de los Mercaderes twists its Gothic columns skyward — the silk exchange where medieval merchants swore oaths and cut deals. Trivia reads the fine print. Then the Palacio del Marqués de Dos Aguas delivers the flourish, its alabaster doorway dripping with baroque excess. Around two hours through Valencia's showpieces. The leaderboard signs the final contract.
