Le Fanu appears to have read an 1836 travel book, Schloss Hainfeld, or a Winter in Lower Styria by Basil Hall, and probably found the description of a pre-industrial and romantic part of Europe an appropriate setting for his vampire novella. By the time Bram Stoker was working on Dracula, he also chose Styria as the home of the vampire count, before deciding to place Count Dracula's castle in Transylvania. The curators of the GrazMuseum believe that at the end of the nineteenth century the construction of a backwards, threatening, and superstitious East Europe had moved further to the Southeast, making Styria a region less likely for a vampire story. Stoker, however, as we know, still retained Styria as a location in his short story Dracula's Guest.
The exhibition at the GrazMuseum appears to explore such themes rather than the vampire's roots in folk beliefs. It consists of five rooms, glimpses of which can be seen in a clip from Austrian TV, from which a few shots are shown below. It is open until Halloween this year, and a publication related to the exhibition will be available later this year.
