Designed by renowned Basque architects and artists, the sanctuary blends spiritual symbolism with avant-garde design, creating a powerful aesthetic that draws visitors from around the world.
Another highlight is the University of Oñate, a beautifully preserved Renaissance structure that was once the intellectual heart of the Basque Country. Visitors can explore its cloisters and marvel at the intricate architectural details that reflect the grandeur of its past. The Church of San Miguel, located in the town center, is a Gothic-style masterpiece, with its imposing tower and richly decorated interior providing a glimpse into Oñate’s religious heritage.
For nature enthusiasts, the Aizkorri-Aratz Natural Park is a must-see. The park offers numerous hiking trails with breathtaking views of the Basque countryside, and the nearby Arrikrutz Cave, an extensive underground labyrinth, is another key attraction for adventurers interested in geology and natural wonders.
