The oldest known documented mention of Altengronau appears in a Latin document, according to which a certain Hainradus bequeathed the village of Gruona above the Gaza River (today: Jossa) to the monastery of Echternach for the salvation of his soul. The document bears the tenth year of Charlemagne's reign as its only dating feature. According to the Luxembourg historian Henri-Camille Wampach's observations on the dating of Echternach documents, Hainradus' donation was dated to the year 780. This date is now generally accepted as the first documented mention of Altengronau.
