The Neumünster Abbey is located in the Grund district of the city of Luxembourg on the banks of the Alzette. During excavations on the site, archaeologists found signs of settlement and handicraft, which apparently date from the twelfth and thirteenth centuries, at the site of what is today the courtyard of the Robert Bruch building. Documents prove that textile craftsmen such as weavers, dyers and walkers worked here on the water in the 14th century. The wooden huts from the second half of the 14th or at the beginning of the 15th century were then replaced by stone workshops. In the 17th century there was a tanning community on the left bank of the Alzette, opposite the church. After the old Benedictine abbey Altmünster was destroyed during the wars between the Kingdom of France and the Holy Roman Empire by the troops of the King of France, Francis I, who occupied the city of Luxembourg on September 11, 1543, and in 1684, when the Troops of Louis XIV, under the orders of Marshal Créquy and Vauban Luxemburg, besieged and shot at, had been badly damaged again, the Benedictine monks erected their new abbey church and the associated abbey buildings in the Grund district in 1606.
