Rick Steves' Europe

Germany's port city of Hamburg, post-World War II, historic sites of Martin Luther and the Reformation, including Erfurt, Wittenberg and Wartburg Castle, and then Wurzburg in Franconia.

The capital city of Dresden, Germany's palaces and art of the Wettin dynasty, and Leipzig's Bach heritage, a monument to the day Europe beat Napoleon and museums.

Frankfurt, Germany, a global hub for commerce. Nuremberg, with its towering castle, fountains, Nazi Documentation Center and underground bomb shelters.

The complex history of Bulgaria, from ancient Thracian tombs to medieval Orthodox Christian monasteries to Soviet monuments.

Romania's capital, Bucharest. Transylvania's fortified churches, cobbled merchant towns and castles, and Maramures region of Romania.

Making prosciutto and pecorino cheese at a farmhouse inn, hiking down ancient wine cellars, and the basilica in Assisi, Italy, the hometown of St Francis.
