Located 35 kilometers (22 miles) northeast of Bilbao, Guernica (Gernika in Basque) is home to the sacred site of the old oak tree Gernika Arbola, where the Basques were granted independence in the middle ages and where they’ve continued to meet for centuries. Also of note is the full-size mosaic replica of Picasso’s painting on Elejalde Street, a tribute to lives lost to war. Visit the world’s largest jai alai court, where locals practice their traditional sport, pelota. At the Peoples of Europe Park, paths wind between large-scale sculptures (find the Henry Moore work) and indigenous trees.
