Note 341 — Chapter XVI · THE CITY OF ROME IN THE MIDDLE AGES.
Reading edition
The last imperial coronation, that of Charles the Fifth, took place in the church of St. Petronius at Bologna, Pope Clement VII being unwilling to receive Charles in Rome. It is a grand church, but the choir, where the ceremony took place, seems to have been 'restored,' that is to say modernized, since Charles' time.
