It may be the financial center of Europe, but that doesn’t mean you’ll be glued to your laptop during a trip to Frankfurt, a city rich in history, culture, and stunning architecture. Set against a dramatic backdrop of skyscrapers, a tour of Frankfurt reveals a fascinating mix of old and new. Saint Bartholomew's Cathedral, Romer City Hall, and the Old Opera House exemplify classic building style; while the Squaire complex, MyZeil shopping center, and the brand-new Seat of the European Central Bank show off the cutting edge of architecture. Frankfurt's other main draw is its proximity to some of the most appealing destinations in Germany. You’ll definitely want to take a Rhine Valley cruise, making sure to sample the region’s wines and and visiting picturesque Heidelberg with its historic old town and castle. Further south, on the edge of the Black Forest, take a refreshing dip in one of Baden-Baden’s hot springs; or go all the way to the French border to visit charming Strasbourg. To the west, the fairy tale–worthy Eltz Castle awaits; while to the east, toward Munich, you’ll find the history-rich town of Nuremberg. When you return from your adventure, spend your final night in Frankfurt checking out its legendary electronic music scene.
