NOTES: Bonomi's design was based on the tomb of Caius Cestius, Rome. The mausoleum as executed in 1796 was a slightly less austere pyramid without the rusticated plinth.
NOTES: The cathedral, also known as the Kaiserdom (Imperial Cathedral), was built by Charlemagne, the first Holy Roman Emperor, in 792-805. The Palatine Chapel, designed by Odo of Metz, holds the remains of Charlemagne (742-814) and was the site of coronations for 600 years.
