Re-creation of a any seen from the past has it problems. As you put it together is it to long? Or maybe to short. Are the walls high enough, or to high? I am making 24 arched openings and I only know for sure what three of them were used for. The other 21, what was in them? For sure windows in some, or all,to allow natural light to brighten up the interior. Were some just architectural details there to continue the visual effect of the repetitive arches. So now i feel that i can do whatever i want within the arches. Some can be windows, some doors, some even blank brick walled up alcoves, even combinations of all these choices. Well we'll soon see what choice is made. It will even be a surprise to me.
