Inaugurated in 1890, the Arriaga Theatre is a Neo-baroque opera house named after the Bilbao-born composer Juan Crisóstomo de Arriaga, often referred to as the 'Spanish Mozart'. Inspired by the Paris Opera House, it became a key cultural venue in Bilbao. The original theatre burned down in 1914 and was rebuilt, reopening in 1919. Today, it hosts opera, ballet, classical concerts, and theatre productions. Guided tours give a behind-the-scenes look at the staircases, Royal Box, and costume collection.

At the top of Mount Vodno in the village of Gorno Nerezi, is located one of the most significant cultural and historical monuments in the region - the charming 12th-century St. Pantelejmon Monastery. Here you have the chance to explore the spectacular series of frescos which present the remarkable Byzantine art.

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.
