Throne of Charlemagne

The Throne of Charlemagne (de: Karlsthron or Aachener Königsthron, "royal throne of Aachen") is a throne erected in the 790s by Charlemagne, as one of the fittings of his Palatine chapel in Aachen (today's Aachen Cathedral) and placed in the Octagon of the church. Until 1531, it served as the coronation throne the Kings of Germany, being used at a total of thirty-one coronations. As a result, especially in the eleventh century, it was referred to as the totius regni archisolum (the Archstool of the Whole Realm). Charlemagne himself was not crowned on this throne.
