Is the Vampire Museum just outside Paris still open? if so, do you need an appointment to get in?
curiosity gets me. What does Paris have to do with vampires? Eastern Europe, yes. Whitby, England, yes. Paris?
(I don't know the answer to either of your questions).
There is a Facebook page, and it looks like they are open by appointment. Le Musée des vampires
No idea if it has anything to do with Paris. My granddaughter, who I’ll be traveling with, is interested in vampires and found something about it on the internet.
