Perched above Bilbao on Artagan Hill, the Basilica of Our Lady of Begoña was built starting in 1511 on the very spot where, legend says, the Virgin Mary appeared. The church mixes styles: mainly Gothic inside, a Renaissance front with a grand arch, and a belfry added in the early 20th century. Inside, there’s a polychrome wood carving of the Virgin of Begoña ('Amatxu' to locals) from the 14th century. Sailors often used to name their boats after her, and every 15 August (Assumption) and 11 October (Feast of Begoña), the place fills with pilgrims.

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.
