Just outside Bilbao, in Biscay, the Vizcaya Bridge (Puente Bizkaia) — also called Puente Colgante or the Hanging Bridge — is the world’s oldest transporter bridge, completed in 1893. It connects Portugalete and Las Arenas (Getxo) across the Nervión River and was declared a UNESCO World Heritage Site in 2006. You can cross either by the gondola, which carries vehicles and passengers in about 90 seconds, or on the pedestrian walkway, accessed via lifts in the towers. The bridge stands 45 m high and 160 m long, and its iron-and-steel design was a milestone of industrial-age engineering.

Built from the late 14th to the 15th centuries, the Santiago Cathedral is the city’s oldest major church, dedicated to Saint James (Santiago), Bilbao's patron saint. The building features a mix of different styles: its core is Gothic (nave, vault, cloister), a grand Renaissance portico was added in the 1500s, while much of the façade and tower with spire were rebuilt in a neo-Gothic style in the late 1800s by Severino de Achúcarro. Inside, you’ll see three naves, several side chapels, the Gothic cloister accessible via the Door of the Angel ('Puerta del Ángel'), and beyond the main altar, there’s an ambulatory with chapels. Floods in 1983 caused damage, but the cathedral was restored and reopened around 2000.
