I want to know the answer to the following question:
What kind of building holds incunabula's today?
All the background I'm provided with is that "As one of the earliest centers of book-printing in Europe (see above: History), Strasbourg for a long time held a large number of incunabula—documents printed before 1500—in her library as one of her most precious heritages.". Is that enough to answer the question?
Answer: no
