Hiya, Bill! Good to hear from ya! And ya brought pictures...
lemme see....
The only thing I fully recognize is the A11 as well. Truth be told, I couldn't even guess what that might be. But I'll take a stab at the others...
I know that the Knights Templar were pretty much all over Europe and beyond during the Middle Ages. I'm pretty sure being that given that as close as they were to Rome (relatively speaking) I'm gonna guess that those crests on the front of the buildings are somehow related?
Of course, this is just a wild stab in the dark...
