Agilbert died at some time after 10 March 673, on which date he witnessed Clotilde's foundation charter for the Abbey of Bruyères-le-Châtel, and probably between 679 and 690. He was buried at Jouarre Abbey where his sister Theodechildis was abbess. His fine sculpted sarcophagus can be seen there in the crypts, as can that of his sister.
