The Throne of Charlemagne is a throne erected in the 790s by Charlemagne, as one of the fittings of his palatine chapel in Aachen and placed in the Octagon of the church. Until 1531, it served as the coronation throne of the King of the Romans, 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 archisolium. Charlemagne himself was not crowned on this throne, but instead in the Old St. Peter's Basilica in Rome by Pope Leo III in 800 AD.
