Catholic Church Conservation has this post about the Monastery of St Florian outside Linz. My Austrian friend of previous post lives in Linz, although she comes from Styria and we have visited this monastery. As it says in the article, Bruckner's favourite organ is in the Chapel and he is buried in the crypt directly below the organ.
I haven't experienced anything iffy there and coming from a country devoid of anything visually Catholic, walking round a city where they have a Guild of Cribmakers just after Christmas was lovely. Different shops with their own cribs in the windows. Great.
Of course, you only see the surface as a tourist and my German not being exactly great, unless you want obscure musical terms, means pretty much anything could be being preached.
