The city was chosen mainly for its cultural heritage — especially as the birthplace of the composer Ludwig van Beethoven.

Bonn celebrates the 250th anniversary of the birth of its most famous son next year, with a ramped-up version of festivities that are held annually in Beethoven's honor.
The city topping the list also comes from the German-speaking world. The Austrian city of Salzburg was chosen for a similar reason that Bonn was: its classical music heritage. The Salzburg Festival, which also celebrates theater and opera, marks its 100th anniversary this year.
Washington clinched second place, followed by the Egyptian capital, Cairo, in third and the Irish city of Galway in fourth.
Rounding out the top 10 were La Paz (Bolivia), Kochi (India), Vancouver (British Columbia, Canada), Dubai (UAE) and Denver (Colorado, USA).
