Long a hub of French culture and cuisine, Paris is one of the most romantic destinations in the world. Over the centuries, Parisian culture has been built on the wings of inspiration. Music, film, architecture, literature, dance and the visual arts all have their brilliant place in the museums, theaters, bookstores and remarkably preserved buildings of this magnificent city. At the center of it all is the Champs-Élysées. With its inviting riverside promenade, graceful bridges and splendid views of all things Parisian, from the Eiffel Tower to the Louvre Museum.

One of the most pleasurable activities in Paris is whiling away the time in one of the city's outdoor cafés. Whether you are sipping a café au lait or a kir royal, there is no better way to feel like a Parisian. The hub of social and culinary life, cafés have been part of the city's fabric since the 1600s. During the 20th century, literary and artistic figures-such as Ernest Hemingway, Colette and Pablo Picasso-famously met over drinks to share their works and ideas. Today, thousands of cafés line the pavements and squares to connect with France's culture and history.

One of Germany's most treasured cities for its rich history, Trier was once the regional capital of the Holy Roman Empire. After Emperor Constantine the Great had a vision of Christ, he and his mother Helena built great churches and cathedrals here. A few still stand, the magnificent Romanesque Cathedral of Trier among them. The 20,000-seat amphitheater, the Roman Bridge and the massive Porta Nigra, the ancient city gate, are further relics of that time. Today, Trier is a picturesque town surrounded by forests and vineyards, known also as the birthplace of Karl Marx and as a vibrant university town.

The historic heart of Trier, the bustling and colorful Hauptmarkt is the city's main gathering place and a rich repository of architecture. Once the center of trade in medieval Trier, the square is anchored by an ornate fountain featuring St. Peter, the city's patron saint. In addition, the unmistakable white- and mustard-colored tower of St. Gangolf Church rises above the square, resplendent with late Gothic and baroque elements. Perhaps the Hauptmarkt's most distinctive building is the Steipe, named for its short pillars. Today, the pedestrian-only Hauptmarkt is a colorful canvas of baroque, Renaissance and classicist styles that mingle seamlessly with modern shops and cafés.

Perched on a hilltop above the city and the Moselle, a 1,000-year-old imperial castle is the signature landmark of Cochem. Its mighty rectangular keep and many small towers strike a dramatic pose against a curtain of green hills. In Cochem's lively Old Quarter, the market square boasts old timber-framed houses that overlook Martin's Fountain and the bay-windowed baroque Town Hall. In this historic center, the 15th-century St. Martin's Church and the Capuchin monastery, which now serves as an artistic and cultural center, are all beautifully preserved. Wine taverns along the river offer a "green wine,” a very young wine.

Koblenz is a traditional German city, founded more than 2,000 years ago. This former trading settlement rests on a massif of the Middle Rhine Highlands. Its cobblestone streets, wood-beamed houses adorned with flowers, ancient market square and medieval churches recall the fairy-tale Germany of old. At the German Corner, a massive equestrian statue of Prince William I observes the lovely riverside scene. The famed Teutonic Knights set up their first base here in 1216. The Romanesque Basilica of St. Castor, Koblenz's oldest building, dates to 836.

Mainz is part of the Rheinhessen wine region, Germany's largest wine region that is renowned for producing high-quality white wines, such as Riesling. Wine has long played a key role in the city's economy and culture, with numerous wine festivals and events throughout the year, including the Mainzer Weinmarkt and the Mainzer Weinwoche. The city is also home to the renowned Geisenheim University, which offers programs in viticulture and oenology. Mainz's wine culture and history continue to thrive today, with a strong emphasis on sustainability and innovation in winemaking.

The quiet German town of Speyer lies on the west bank of the Rhine. The city features a Romanesque imperial cathedral, burial place of eight emperors including some of the most famous Holy Roman Emperors. Speyer was once a major Celtic center that traded hands several times between the Romans and the Huns. The term Protestant originated here at the Diet of Speyer in 1529, when 14 free cities of Germany and six Lutheran princes protested the Edict of Worms that had banned the writings of Martin Luther and labeled him a heretic and enemy of the state.

The largest port on the Upper Rhine, Strasbourg is the cultural center of France's Alsace region. Thanks to its location at the border of France and Germany, it boasts a convivial mix of cultural influences. The well-preserved old town is enclosed on all sides by the little Ill River, with sites so compact that it is easy to explore the "island” on foot. And there is plenty to explore: cobblestone streets lined with wooden houses and intersected by picturesque canals. Indulging in Alsatian café culture is central to any visit here; enjoy coffee and cake amid lovely half-timbered houses.

Located where Switzerland, Germany and France meet, Basel reflects a fascinating blend of traditions. The city straddles the Rhine at the river's farthest navigable point, and an alluring cluster of old-town buildings huddles along the riverbank. Around Market Square, guild houses recall Gothic, Renaissance and baroque splendor; the red-sandstone Rathaus, or Town Hall, is the centerpiece. More than 40 museums of art and culture lend modern polish to its history-rich streets. And there is no more refined way to sample it all than over cheese fondue or croissants.

Zürich offers much more than its reputation as a city of banking institutions. The Grossmünster is one of Zürich's most important landmarks and the center of the Swiss Reformation in the 16th century. Across the river lies Fraumünster, famed for its stained glass windows painted by Marc Chagall. Exclusive designer boutiques line the streets of Storchengasse alongside world-renowned chocolatiers and quaint, cozy cafés. The scent of delicious sweet treats and freshly baked gipfeliwaft through the air on every street corner.
