Sanctuary of Arantzazu (Santuario de Aránzazu)

Clinging to a cliff within the Aizkorri mountains, the Sanctuary of Arantzazu (Santuario de Aránzazu) is a modern architectural marvel that blends Franciscan spirituality with avant-garde Basque art. The sanctuary’s origins trace back to a miraculous event when the Virgin Mary appeared in a hawthorn bush, leading a shepherd to ask, ‘Arantzan zu?’ (‘Is it you in the hawthorn?’). Today, visitors can explore this unique site, which not only serves as a significant religious landmark but also showcases an impressive collection of contemporary Basque artwork.
