Elchingen Abbey
Elchingen, Germany · built 1128
Elchingen Abbey (Kloster Elchingen, Reichsabtei Elchingen) was a Benedictine monastery in Oberelchingen (in Elchingen) in Bavaria, Germany, in the diocese of Augsburg. For much of its history, Elchingen was one of the 40-odd self-ruling imperial abbeys of the Holy Roman Empire and, as such, was a virtually independent state that contained several villages aside from the monastery itself. At the time of its secularisation in 1802, the abbey covered 112 square kilometers and had 4000-4200 subjects.
