Guglielmo Marconi Airport serves the Italian city of Bologna. If you hire a car here, you'll find that the airport is four miles to the northwest of the centre. The handy A1 an A14 motorways provide easy access to destinations all over northern Italy, while smaller roads can lead you to the Bologna ring road and into the historic centre. The complete SS64 ring road is useful for local access but beware that the ancient grid of narrow streets within it can be difficult. Nevertheless, it's worth exploring, as Bologna is one of Italy's great unsung attractions.
