The second-largest city in Bavaria, Nuremberg is filled with traditional half-timbered houses and Gothic churches with intricate spires. Although nearly destroyed during World War II, the remaining medieval city walls stretch some three miles and feature original gateways and 80 original watchtowers. Nuremberg is well known historically for its metal and toy craftsmanship. But it is infamous for its role in World War II, first as the site of Zeppelin Field's Nazi rallies and later as the site of the war crimes trials at the Palace of Justice that captured the attention of a generation.

Founded in 902, Bamberg remains a medieval-looking city known for its symphony orchestra and rauchbier, specialty smoked beer. The city's winding streets are filled with baroque patrician houses and are home to the stunning 11th-century Cathedral of Holy Roman Emperor Heinrich II, housing his tomb and that of Pope Clement II. Bamberg is especially noted for its Altes Rathaus, or Old Town Hall, situated on a twin-arched bridge over the Regnitz River, and for the old bishop's houses: the 16th-century Alte Hofhaltung (Old Court) and 17th-century Neue Residenz (New Residence).

Surrounded by Franconian vineyards, Würzburg was heavily damaged during World War II, but has since been completely restored. This prestigious university city is a jewel of baroque architecture. Its most pristine example of pomp and glory is the great Bishops' Residenz palace, built in 1744 for the prince-bishop; his unwavering support of artists is evidenced by the sweeping staircase and magnificent ceiling frescoes by Tiepolo. Other landmarks include the medieval, statue-lined Old Main Bridge and Marienberg Fortress, originally a Celtic hill fort and later residence of the bishops. The city remains a major wine-making center, hosting Germany's oldest and largest vineyard.

Situated at the confluence of the Main and Tauber Rivers, Wertheim is a charming town brimming with history. The dukes of Wertheim built a castle at this strategic spot in the 12th century. It was captured and destroyed during the Thirty Years' War, but it is still impressive today, peering down upon the medieval town center and half-timbered houses from its perch. Its Pointed Tower has guarded the junction of the Main and Tauber Rivers for 800 years. Known as a successful merchants' town during the Middle Ages, today Wertheim is famous for its Franconian wines.

The Rhine River flows through one of Germany's most scenic regions. As you sail its most picturesque stretch, the UNESCO World Heritage Site of the Middle Rhine, you will pass vineyard-blanketed hills whose steep slopes require vintners to pick grapes by hand, keeping a centuries-old tradition alive. Splendid castles line the banks, all of which have stories to share, and the Lorelei Rock presides at a dramatic curve in the river. This infamous river maiden mesmerized sailors with her song and lured them to their demise at her feet.

Cologne reveals its Roman heritage in its city layout and the ancient ruins that lie scattered through the town. Cologne's modern plazas and Hohe Strasse host welcoming shops, enticing restaurants and cologne boutiques. Of note is the city's 13th-century cathedral, a stunning example of Gothic artistry and a UNESCO World Heritage Site. Having survived Allied bombs during World War II, the cathedral's imposing twin spires are visible for miles and its stained glass windows fill the interior with brilliant colored light. Its steps lead to a platform with astounding views.

Kinderdijk is a village community in the Alblasserwaard province. This corner of South Holland, part of the scenic Waal and Merwede regions, has long been shaped by Rhine Delta waters. Kinderdijk is most known for its 19 remarkably preserved 18th-century windmills. The charming hamlet is located amid low-lying polders, tracts of land reclaimed from the sea by the power of the windmills and enclosed by embankments, or dikes. This legendary place calls to mind the 1865 novel Hans Brinker, in which a heroic boy plugs his finger into a ruptured dike.
