Linz is an industrial city (with huge steel and chemical works) which was bombed during World War II - and was one of the few cities of Nazi-Germany that escaped total destruction. While Linz does indeed have a sizable "Altstadt" (old town) it may be disappointing to those tourists familiar with the charm of Graz or Salzburg. Linz is primarily a student and industrial town and while not particularly beautiful, is more representative of a "real" Austrian city vs. the almost fairy tale like quality of Salzburg. While industry in Linz is still financially important, it is slowly diversifying by helping small companies and encouraging tourism. The city gets a lot of international media attention because of its annual Ars Electronica Festival
http://www.aec.at; an international festival for Electronic Art. It also hosts the "Klangwolke" ("sound-cloud"); a big cultural Open-Air spectacle with modern and traditional music and a massive light show, which is held in September. Linz will become the "European Capital of Culture" in 2009, by virtue of an independent cultural development and an innovative culture and art scene. http://wikitravel.org/en/Linz
