Charlemagne's palace, the era of coronations and the tradition of pilgrimages have produced an unique and magnificent church treasure whose most famous pieces are on show today in the Cathedral Treasury. The oldest piece is a Roman sarcophagus which portrays a scene from ancient mythology, and in which Charlemagne was initially buried. From Charlemagne's palatine school in Aachen comes a book cover carved from ivory and showing scenes from the story of Christ's resurrection. According to medieval legend, several other pieces of the Cathedral treasure belonged to Charlemagne himself, one of them a hunting horn fashioned from the tusk of an elephant.
