MAXXI, Italy's first national museum devoted to the arts of the XXI century and designed by Zaha Hadid, is a platform open to all forms of contemporary creativity, from art to architecture, from photography to design, from fashion to cinema. A place for meetings, exchange, and collaboration.

Check out the magnificent caves at Puente Viesgo (24 kilometres from Santander), where stalactites and stalagmites stretch among incredible prehistoric paintings. The village itself is also worth a look around. Tours start at the visitor centre 1.5 kilometres above the village.

Named after the nearby Embassy of Spain, the Spanish Steps link Piazza di Spagna with Piazza di Trinità dei Monti. The 135-step stairway is especially striking in spring, when azaleas bloom along the balustrades. The steps became famous all around the world thanks, in part, to Audrey Hepburn's film "Roman Holiday" and Bob Dylan's song "When I Paint My Masterpiece". Sitting on the steps is now prohibited, but the view across the piazza and the surrounding streetscape remains one of Rome’s most recognisable sights.

If you like history and discovering beautiful libraries, you're in for a treat. On this fascinating tour, you start with a visit to Dublin's Trinity College Library, home to the famous Book of Kells—the lavishly illustrated manuscript of the Gospels dating back to AD 800 and widely considered among the most important of all of Ireland's ancient treasures. Then, enjoy a guided tour around the grounds of Dublin Castle, and listen to fascinating stories of its years as a prison, military fortress, and the seat of the English Administration in Ireland.
