A previously unknown Constantinian basilica has recently been excavated in Sofia, Bulgaria. No meaningful photos at link. If I hadn’t already made and distributed the take-home final I would turn this into a question for Arth 270: Art and Architecture of the First Christian Millennium. Something like:
The deputy mayor would like the discovery of this substantial basilica to mean that Serdica (Roman Sofia, Bulgaria) was in the running with Byzantion to be Constantine’s Nova Roma. Examining our list of the buildings Constantine did build while turning Byzantion into Constantinopolis (and don’t forget the walls!), evaluate this claim.
Oh well, lucky them!
