A charmer of a daytrip, with history stretching back to the ancient Romans.
A small and charming city.
In the northwest of Austria, the small city of Linz (pop. 200,000) is one of the prettiest daytrips you can take from Vienna, two hours away by train (and while you can do it in a day, an overnight is worthwhile, if you can spare the time). Its origins actually hark back to the origins of the country itself, founded as it was by the Romans as a trade entrepôt; to this day, classical ruins can still be seen in its streets. The city's most important building is the Altes Rathaus (Old City Hall), built in the early 16th century after a fire reduced the city to ashes. Interestingly, one of the main events of the year in this small, ancient, and out-of-the-way city is the site each September of one of the world's most important annual electronic music festivals, Ars Electronica (the reason being that the sponsoring foundation is based here; you can visit its museum year-round).
