Commonly called the Puente Colgante (Hanging Bridge), this has been one of Bilbao's most extraordinary sights ever since it was built in 1893. The bridge, a transporter hung from cables, ferries cars and passengers across the Nervión, uniting two distinct worlds: exclusive, bourgeois Las Arenas and Portugalete, a much older, working-class town. (Dolores Ibarruri, the famous Republican orator of the Spanish civil war, known as La Pasionaria for her ardor, was born here.) Portugalete is a 15-minute walk from Santurce, where the quayside Hogar del Pescador serves simple fish specialties. Besugo (sea bream) is the traditional choice, but the grilled sardines are hard to surpass. To reach the bridge, take the subway to Areeta, or drive across the Puente de Deusto, turn left on Avenida Lehendakari Aguirre, and follow signs for Las Arenas; it's a 10- or 15-minute drive from downtown.
