"In the fields around Molsheim" originally meant Altorf, and was part of the domain of the Counts of Colmar, one of the most powerful families of the Holy Empire.
The strategic and administrative center of this vast territory was the stately castle Girbaden. At this point, Altorf was not a village, but rather a group of scattered farms. It was later that Alt (old) and Dorf (village) of German origin takes its name Altorf. But the town is best known for its abbey.
