Ibiza Town is the capital of Ibiza, one of Spain's Balearic Islands in the Mediterranean Sea. It's known for its lively nightlife scene, and many European nightclubs have summer outposts here. South of the center, Ses Figueretes and Platja d'en Bossa are white-sand beaches. Above the harbor is the old quarter of Dalt Vila, with the Gothic-style Catedral de Santa María and views from Renaissance-era fortifications.
