15thc perception on swallowtail merlons?

[Koen G]

Castles added, apart from Blonay. There was a tower in the 12th century (which may not have had the merlons) but the main construction was carried out in the 15th century. If this was done before 1450 it should be added of course, it would be one of our most western castles so far.

Now I don't know when the ghibiline merlons were added. I would be very surprised if they date from after 1469. They probably date from after 1430 and before 1469.

This is a risky one to assess without a lot of research - you can see that the top bricks are newer than the layers beneath.
