in the middle of the 18th century shows that Molsheim Charterhouse owned land in nearly 100 places: in the vineyards of the Vosges foothills (from Dambach-la-Ville to Marlenheim), in the wet lowlands of the Ried, between Benfeld and Erstein, in the cereal-growing lands of the Kochersberg, mainly north of Truchtersheim, around the Haguenau forest, mainly in Soufflenheim, Bischwiller and Betschdorf, and finally in Outre-Forêt, near Niederbronn. A few rare possessions were located in distant Rhine regions, in Trier, Mainz, Baden and Durlach. These possessions were mainly located (42% at the time) in lands under the sovereignty of the archbishop of Strasbourg, mainly those around Dachstein, Benfeld, Schirmeck and in the Kochersberg. 11% were located in lands under the seigniory of Choiseul-Stainville, mainly near Haguenau; another 11% were attached to the County of Hanau-Lichtenberg, which was then under the control of the Landgraviate of Hesse-Darmstadt; another 11% belonged to various nobles of Lower Alsace. The remaining quarter was under the authority of the free imperial city of Strasbourg, or the cities of the Décapole, or abbeys or chapters in the region. Approximately three quarters were located in Catholic localities, but almost a quarter in Protestant areas; this was obviously not the case at the time of the 1598 exchange.

The latter were located on the least productive land, mainly in the main riverbed of the Bruche. The river diversions carried out by Vauban also meant that the community lost a significant part of the meadow land it had. The meadows, generally divided into long and narrow plots, were located in the plain, towards Dorlisheim in the south, Altrof in the south-east and Avolsheim in the north.

Carthusian handicrafts In the 18th century, the Carthusians of Molsheim were known in the region for the production of their medicinal "balls". The exact composition is now lost, but at least some elements are still known. The balls included at least potassium bitartrate, iron, frankincense, myrrh and resin mastic. These substances were crushed in a mortar and mixed to form a paste that had to
