Frankfurt Cruises, Germany

You might hear Frankfurt referred to by another name – Mainhattan, alluding to the city’s setting on the Main River, as well as its futuristic skyline. But, mixed in with the new, there are timber houses and red-brick churches. Lots of the city was damaged in World War Two, but it’s since undergone a huge restoration project. Römerberg square’s now lined with traditional, Medieval-style buildings. Palmengarten is Frankfurt’s version of Kew Gardens, with zones dedicated to rainforest, sub-Antarctic and desert plants. And the 200-year-old Städel Museum houses artworks by Van Gogh, Monet and Rembrandt. Get a feel for Frankfurt on the Ebbelwei Express tram, which does a circuit of the city, rattling past the zoo and Römerberg.
