Frankfurt is a city of business. Host to international trade fairs since the 13th century—and now home to the European Central Bank—this capital of finance has more than a glint of hypermodern efficiency about it. But it isn’t all glass skyscrapers. Here, you’ll also find half-timbered treasures like the Römer (Frankfurt’s City Hall), the rustic cider (apfelwein) taverns of Alt-Sachsenhausen, and museums like the Goethe House and Senckenberg Natural History Museum. Then there are green spaces like the Frankfurt City Forest and Botanical Garden, and cultural venues like the Old Opera House. And when planning things to do in Frankfurt, don’t forget that the Rhine—and its many castles and wineries—is just a few dozen miles away.
