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.

The Atsuta Shrine is one of the most important sacred places in Japan, ranking second only to the Ise Shrine. It stores one of the so-called Imperial regalia, the sacred sword Kusanagi, and is well known for its peaceful and relaxing atmosphere.

This museum features paintings and sculptures from the Middle Ages to the 20th century along with departments of archaeology, natural history and ethnology, and a vivarium with fish and reptiles. While the exhibitions themselves attract visitors of various interests, the housing monument is also well worth a glance.
