4 Best Sights in Bilbao and the Basque Country, Spain

This extraordinary 19th-century transporter bridge suspended by cables ferries cars and passengers across the Nervión, uniting the bourgeois Arenas and working-class Portugalete districts.  Portugalete is a 15-minute walk from Santurce, where the quayside Hogar del Pescador Mandanga serves simple fish specialties like besugo and grilled sardines.

This footbridge just downriver from the prow of the Mercado de la Ribera was traditionally known as the Puente del Perro Chico for the 25-cent coin once charged as a toll for crossing. Until Calatrava's Zubizuri was built, this was the only pedestrian bridge of Bilbao's nine river crossings. The bridge is officially named the Puente-Pasarela Conde Mirasol for the street it leads into.

Many of Logroño's monuments, such as this elegant bridge, were built as part of the Camino de Santiago pilgrimage route.

Santiago Calatrava's seagull-shaped bridge (the name means "white bridge" in Euskera) is a few minutes from the Guggenheim. Other creations by the cult architect include Bilbao Airport and Ondarroa's Puerto Bridge.
