Take a tour of Peñafiel Castle in Spain – part of the World’s Greatest Attractions travel video series by GeoBeats. Perched on the hill crest of Penafiel Spain rests an ancient and stately castle. This is the aptly named Penafiel Castle, whose design, because of the shape of the hill, is similar to that of a boat. This prominent and expansive structure was built between the thirteenth and fifteenth centuries. It was originally built by one of Spain's wealthy nobles to be the “Faithful Rock of Castile”. The view from the keep and walls looks out over Penafiel and two beautiful valleys. The interior of Penafiel Castle is accessible to visitors via guided tours.
