The definition should not be too strict.
For example I imagine some kind of order within the places:
"Architecture": Fulcanelli's places, House Flamel, Some houses in prague,....
"Rare and original books": the libraries where to find them.
"Art": Museums, exhibitions with alchemical content
There should be a short description of what to find at a place.
Edit:
What I think wouldn't be helpful is something like "I felt a special kind of energy at that place near a tree in the black forest."
Though we can talk about if we want to have these kind of places collected in another subgenre like those above.
Another not useful thing to do might be to locate all possible hermes/mercury statues or churches with pictures of the holy trinity. But on the other hand, why not? What do you think?
