Swallowtail merlons... or provenance

[Paris]

May I suggest the three castles in Bellinzona, Switzerland might have had a resemblance to the buildings in the VMS in the early 15th Century (they still do now) and still have swallowtail merlons - always have, I think?

Thank you.

I think it's a good suggestion, don.

Bellinzona is a medieval city located in south of Switzerland and protected by three castles (Castelgrande, Montebello and Sasso Corbaro).

Once again the castle in VMS (Rosette page).
   

And now, two pictures of the three castles.
   
   

I'm not writing these castles are the same that the one in the VMS but just that the two kind of merlons can still exist in a same castle.


Last thing interesting, but it's probably a coincidence, the coat of arms of this city (Bellinzona) is :
   
This coat of arms makes me think to the snake in folio 43v.
