If it wasn’t so interesting, I would say: an eyesore for Altengronau… packed behind a construction fence

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.

In contrast, more recent research suggests that Charlemagne's reign as king began as early as 768. After Charlemagne's father, Pippin, died on September 24, 768, an assembly on October 9 elected his sons, Charles and Carloman, joint kings of the Frankish Empire; Carloman ruled the southeastern part of the empire, while Charles ruled the other part. Following this interpretation, Hainradus's deed of gift, and thus the first documented mention of Altengronau, can be dated to 777 or 778.

At the Gerhausen marble works in Altengronau, approximately 200 employees cut and processed stones from all over the world. In 1985, the company was forced to file for bankruptcy.
