I’d guess 120-150 in the 1950’s. As the thing has been in ruins and rebuilt many times before, present size is no indication of how big it was in 1200. I’d guess that it peaked between 1200 and 1347.

I had to look up why you selected 1347. Seemed Spock like. That is when the Bubonic Plague reached Europe. Very impressive.
