La Lonja de la Seda

The UNESCO-listed Silk Exchange in the old town — a late-Gothic masterpiece whose great hall is held up by spiraling, palm-like columns that twist toward the vaulted ceiling, built when Valencia was a Mediterranean trading power. The main trading hall is one of the finest secular Gothic interiors in Europe, with a tranquil orange-tree courtyard alongside. For visitors, it's an essential stop — a monument to the medieval merchant city, where the soaring twisted columns create an almost forest-like space, and the craftsmanship speaks to the wealth that silk and trade once brought to Valencia.
