It may be most famous as a convention centre with its annual motor show and book fair, but there is a great deal on offer for the tourist hiring a car in Frankfurt. Sitting on the Main River in south western Germany, it’s the country’s 5th largest city and is an important financial centre that’s also home to the European Central Bank. After the Second World War much of the city was rebuilt, but many of the original structures were saved. It was also the birthplace of Johann Wolfgang von Goethe, a famed German writer – a fact that’s reflected in the name of the city’s university.
