Chillida-Leku is an open-air museum near the city of Hernani, about an hour and a half from Bilbao, dedicated to the Basque sculptor Eduardo Chillida. Around 40 of his monumental steel and granite works are dotted through meadows and woodland, with smaller pieces displayed inside the restored 16th-century Zabalaga farmhouse. The grounds are peaceful and easy to wander, and there’s also an organic café and shop on site.

The Cube Houses (Piet Blom, 1984) are part of the Blaakse Bos (Blaakse Wood) development which borders on the Laurenskwartier district and the Waterfront area. The architect wanted to design a kind of village within the city and saw the houses as trees and the whole area as a wood. The Cube Houses are tipped to one side as it were, making three sides face the ground and three face the sky. Don’t forget to visit the Kijk-Kubus (Show-Cube) to experience what life is like in a Cube House.

Crowning Girona’s skyline, the Cathedral of Santa Maria commands attention from the top of a majestic 86-step staircase. Its soaring Baroque façade, added in the 17th century, belies a far older history: foundations date to the 5th century, with a Romanesque church and 12th-century cloister still preserved within. The cathedral’s most notable feature is the 23-metre-wide Gothic nave (widest in the world!) completed in the 14th century and illuminated by vast stained-glass windows. Inside, the Museum of the Cathedral safeguards extraordinary treasures, including the 11th-century Tapestry of Creation, a vivid Romanesque depiction of divine order, and a gem-studded 14th-century silver altarpiece. The cloister captivates with carved capitals portraying biblical tales and mythical beasts. For context, use the included audio guide to unravel layers of history, from Roman forums to medieval masterpieces.

The Santa Clara Monastery & Museum has a long and interesting history, from being an Arab palace to becoming a monastery. The museum holds an exhibition of archaeological remains and religious art.
