15thc perception on swallowtail merlons?

[Mark Knowles]

Any building or wall will do, it's just about the architectural feature. Is it known if the abbey's merlons are originally pre-1450?

I think they are probably pre-1450 (certainly pre-1500). I think they are post-Voynich. I can investigate their date if important.(There is a book about the architecture). I expect they would have been constructed between about 1428 and 1469 when Abbot Barbavara was Abbot.
