Would be interesting to see the original architectural drawings. I wonder if they exist?

I doubt if the plans still exist. No doubt there were initial plans of some type, but with medieval churches being built over a couple of hundred years, if on a ‘rush’ schedule, there were probably many changes and lost copies.

And I’m sure Fr. Esser made a comment about that during our Art History mandatory classes or in the medieval history class from Fr. Gerlach, but that was nearly 50 years ago and my memory banks are failing.

I just noticed that the drawing you posted states that it is a “Chatderal” and not a “cathedral.” I wonder what the difference is? Perhaps something going back to medieval religious spats? Oh well, such a worry is probably ‘medieval’ in nature and useless now.
