Portugal has an oversized history, fascinating culture, and boatloads of sardines. Saving the capital city of Lisbon for another episode, Rick dances on the beach at Nazare, marvels at a medieval abbey in Batalha, visits a royal library and revels with university students in Coimbra, savors port wine with the people who made it along the Douro River, and gets to know Portugal's gritty and fascinating second city, Porto.
