Prague is known as the "City of a Hundred Spires” and it is easy to see why. The towering twin steeples of Týn Church and the beautiful baroque Church of St. Nicholas are among some of the city's most notable. Best explored on foot, Prague's Old Town is a maze of ancient cobblestone lanes with the Old Town Square at its core. Here, the medieval Astronomical Clock still chimes today and provides for its viewers a little theater with the "Walk of the Apostles” on the hour, every hour.

Few cities embody the past as authentically as Prague, the Czech Republic's atmospheric capital on the Vltava River that clings to its history with unwavering passion. Prague's medieval architecture is its most prominent, but the city is also a rich repository of Romanesque, baroque and art nouveau buildings that stir the imagination. The city's graceful, pedestrian-only Charles Bridge served as the coronation route of the kings of Bohemia across the river to Hradčany Castle and its rich complex of royal buildings.

The Czech town of Děčín enjoys a pastoral setting amid green hills. The 13th-century king of Bohemia Ottokar II invited northern neighbors to settle here, forever giving the town a German flair. Though the 1945 Potsdam Agreement expelled postwar Germans, Děčín embraces its heritage in many of its architectural treasures, including its namesake castle and the 1906 buttercream- and azure-colored synagogue, the only surviving structure of its kind in the former Sudetenland. Děčín's elegant beauty was inspiration for Polish composer Frédéric Chopin.

Sail through the magnificent, soaring rock formations of Saxon Switzerland. This spectacular region earned its name from two Swiss painters who were reminded of their home while visiting. You will witness some of the wildest cliff formations imaginable, with nicknames such as Catapult, Locomotive and Wolf’s Ravine. As you pass through, marvel at the Bastei, a 1,000-foot spectacle of tooth-like rocks connected by a footbridge. Sailing past these iconic monoliths is sure to be a highlight of your journey.

The scent of gingerbread, aromatic glühwein and roasted chestnuts has been filling the air of Dresden’s Old Market Square since the mid-15th century. Traditional crafts, such as Ore Mountain folk art, Lusatian blue-printed fabrics and Moravian stars, are popular gifts, as is the city’s famous Dresdner Christstollen, a delicious spiced fruit loaf. Each year, a festival dedicated to the regional specialty takes place, where a giant stollen weighing several tons is presented to the town and sold to raise funds for charitable causes.

Surrounded by idyllic wine villages and set at a rocky spur on the Elbe, Meissen dates back more than a thousand years. The city is dominated by its 13th- and 14th-century Gothic cathedrals and Albrechtsburg Castle, perched on a low hill, considered one of the great achievements of German architecture. The introduction of porcelain here by Johann Friedrich Böttger in the early 18th century made Meissen world famous. Meissenware has been produced here ever since. Across the city, the chimes of the Gothic Church of Our Lady’s bells can be heard; they were the first church bells made of porcelain.

Wittenberg is an important center of culture and learning, known mostly as the birthplace of the Protestant Reformation. It was here that the Augustinian monk Martin Luther famously nailed his “95 Theses” against the selling of indulgences to the door of the palace church in 1517, launching the spread of a new religious movement throughout Europe. Wittenberg’s incredibly preserved Old Town was spared destruction during World War II, and so its charming houses remain as they have for centuries, with those in the market square huddled around the beloved statue of Luther.

Potsdam straddles one of the Elbe’s main tributaries, the Havel River. It boasts a rich history that spans more than 1,000 years. From its humble beginning, Potsdam burgeoned into a royal city, hosting the residences of Prussian and German rulers until the early 1900s. A series of tumultuous events followed, but through it all, Potsdam maintained its prominent stature. And in 1990, with Germany’s reunification, Potsdam was named Brandenburg’s state capital. Today, the city’s regal past lives on in its 16 well-preserved palaces and three elegantly landscaped parks.

Berlin is one of Europe's most cosmopolitan and forward-thinking capitals. When the Berlin Wall fell in 1989, a sweeping transformation took hold and is powerfully symbolized in the Reichstag, Germany's parliament building. Monuments of wartime are everywhere here, from remnants of the wall to Checkpoint Charlie. Prewar treasures include the baroque Charlottenburg Palace and 13th-century St. Nicholas Church. Straddling the Spree River and peppered with grand theaters and more than 170 museums-many of them on Museum Island-today's Berlin is a major cultural center.
