On one of the nicest stretches of the Turia riverbed is this huge glass vault, Valencia's main concert venue. Supported by 10 arcaded pillars, the dome gives the illusion of a greenhouse, both from the street and from within its sun-filled, tree-landscaped interior. Home of the Orquesta de Valencia, the main hall also hosts touring performers from around the world, including chamber and youth orchestras, opera, and an excellent concert series featuring early, baroque, and classical music. For concert schedules, pick up a Turia guide or one of the local newspapers at any newsstand. To see the building without concert tickets, pop into the art gallery, which hosts free changing exhibits.
