The goal of the 780km Camino de Santiago pilgrimage — millions have walked or cycled to reach this great cathedral where St James (Santiago) is said to be buried. The ornate baroque facade (the Obradoiro) conceals a Romanesque interior. The Pórtico de la Gloria — a masterwork of medieval sculpture by Maestro Mateo — is one of the most important artistic achievements in Europe. Pilgrims queue to embrace the saint's silver bust.
