The first written evidence of Esch-sur-Sûre is found in the "Liber aureus Epternacensis”, the golden book of Echternach abbey according to which a certain Nebelungus is said to have donated his properties and serfs to the abbey. This act was written in the third year of Charlemagne's reign, between 9th October 773 and 9th October 774. On 3rd June 927, Meginaud (aka Maingaud) acquired the site of Esch-sur-Sûre in a deal with the abbey of Stavelot. He erected an 8x8 metre square residential tower as well as buildings for agricultural use.
