Frankfurt am Main is the city Germans call "Mainhattan" — the only true skyline in the country, where glass banking towers rise straight out of a river town that has been trading since Roman times. It is Europe's financial capital, yet a few streets from the trading floors you are back among half-timbered gables, a coronation cathedral, and taverns pouring tart apple wine from stoneware jugs. That collision of eras is what makes Frankfurt so rewarding to explore with self-guided audio tours: almost every corner hides a longer story than its facade lets on, and the guides tell it as you stand there.
Where emperors were crowned
Start on the Römerberg, the old market square Frankfurt painstakingly rebuilt after the Second World War. The three-gabled Römer has served as the city's town hall since 1405, and nearby the red-sandstone Frankfurt Cathedral — the Kaiserdom — hosted the elections and coronations of Holy Roman Emperors, ten of them from 1562 onward; the fit can climb its 328 tower steps for the view. Between cathedral and square stretches the reconstructed Dom-Römer quarter, a brand-new old town whose lanes are best unpacked landmark by landmark, each audio guide tracing a story of destruction and return. Round it off at St. Paul's Church, remembered as a cradle of German democracy, and the house where Goethe was born in 1749.
Mainhattan from above
For scale, ride up the Main Tower: its open-air observation deck sits 200 metres above the banking district, the whole contrast of spires and skyscrapers at your feet. Back at ground level, cross the Eiserner Steg, the iron footbridge that delivers the classic postcard shot of the skyline reflected in the Main.
A riverbank of museums
Few cities concentrate culture like the Museumsufer, the museum embankment lining the Main with dozens of institutions — film, architecture, world cultures — crowned by the Städel Museum and its 700 years of European art, from Botticelli and Rembrandt to Monet and Picasso. When you need green, the Palmengarten botanical garden folds greenhouses, exotic plants, and small lakes into the city's west end.
Apfelwein and market stalls
End south of the river in Sachsenhausen, where winding cobbled lanes shelter the traditional taverns serving Apfelwein from clay Bembel jugs — or graze your way through the Kleinmarkthalle, a covered market of more than 150 stalls where locals buy regional cheese and dare visitors to try Handkäse mit Musik. Banking capital it may be, but Frankfurt rewards the curious ear at every turn.
