I live in a town which burned in 1904 and was rebuilt with financial support from Kaiser Wilhelm II. In Art Nouveau style, since that was the trend at the time, but also in fairly cheap Art Nouveau, since it wasn't a rich town. So it has a lot of Art Nouveau buildings, but individual Art Nouveau buildings are much prettier in Prague, Barcelona etc. There is ornamentation, sure, but not that much. I think the mediocre stuff is still pretty nice.
