Do you want to or have to?! If former, don't bother, there's nothing to see, there're lots more interesting places to visit in Germany.

visiting Frankfurt..I lived there for six months..I have to say i did not see anything really exciting during the day time..maybe the zoo...

But...If you're into clubbing...Robert johnson is the best club i've ever been to..said to be the cradle of minimal music..you can also check the cocoon..posh atmosphere but the design is quite impressive..the club was founded by the electronic legend sven vath.

Hi,

I am from Frankfurt. You can visit the Frankfurt shopping "mile" called Zeil and walk towards the Opera, where you will be very close to the Banktowers. Go the Goethe-Haus (the poet Goethe was born there), have a fantastic view from the Maintower, visit Alt-Sachsenhausen at night (old part of the city with many bars),the Römer-are (old buildings, the town hall, the cathedral "Dom" where the kings of the Holy Roman Empire were coronated, the Pauls Church, where the first Geman Parliament was constituted in 1848, a lot of museums (e.g. Historical Museum, Senkenberg-Museum, Botanic garden, Zoo), relax on the riverbanks, drink applewine, have a boat-tour.

More information in English and other languages available:
