319 San Pietro in Vaticano
744 Fulda Abbey Church, etc.
I never knew that the original(?) Fulda Abbey Church was such a close reenactment of the original St. Peter's. And now I'm wondering how much the Catherdral at Speyer reenacts the original "Constantinian" double basilica at Trier. [Treves, today's Trier, was Constantine's imperial capital of choice before Constantinople.] Could it be that Romanesque might just really be "Trieresque"?
