Two episodes plus bonus clips: Medieval Europe: Moody ruins, tippy towers, cobbled streets, sparkling mosaics, monasteries, castles, and cathedrals are the stuff of tourist dreams. We revisit some favorites and a few new sights as we make sense out of a fascinating thousand years--from the fall of Rome to the dawn of the Renaissance. We sort it out with short itineraries in Ireland, Austria, Germany, and France. Four Great Cities of Europe: London, Paris, Amsterdam and Brussels. Big cities are hubs of commerce and the arts, energy, surprises, and international flavor. Where do you start if you have just 24 hours? We highlight best choices in four great cities. London calls for tea at the Athenaeum and art at the New Tate. Paris treats us to impressive dining, the Musee D'Orsay and the Pompidou. Rembrandt's The Night Watch and traditional rijsttafel dinner are mandatory in Amsterdam. In thousand-year-old Brussels, we land in the most beautiful town square in Europe. Europe's great cities stay with you.
