Aachen Cathedral (Kaiserdom): the upper part and dome of the Palatine Chapel

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. The gables were added in the 13th century while the dome was built after the fire of 1656.
