Mitteleuropa - Cities in the Centre of Europe
Once upon a time, Vienna was the centre of the (Western) world. Here is a list of cities with more than 100,000 inhabitants located within 500 km from Vienna, in order of distance from the city. Nowadays, they belong to twelve different countries, but at one time or another I think all of them belonged to an empire ruled from Vienna. How many of them have you visited?
