Claudia arranges a one–of–a–kind tour of architect Antoni Gaudí’s most famous buildings. Mark and Mario head west to the rugged region of Asturias. The boys stop in Oviedo for some local sweets before reaching the mountains. They visit the hilltop town of Covadonga for a little religious history. Further in the countryside, Mario and Mark enjoy a meal from a heartwarming Asturian home cook.
