Foundation Information
 

The convent was founded by Henry and Mechthildis, count and countess of Sayn. According to a necrologium drawn up by the nuns of Sion in the seventeenth or eighteenth century on the basis of older records, the convent was established in 1215. No foundation charter has survived. No early documents, dated prior to 1244 have survived either, so little about its early history is known. Sion first followed the Benedictine Rule according to Cistercian customs before being actually incorporated into the order. In 1248 or 1249 the convent was formally incorporated into the Cistercian order at the behest of Pope Innocent IV.

 
Population Counts
 

The convent was so popular that Pope Innocent IV limited the number of inhabitants to 50 in his confirmation bull (McDonnell, 94).

 
Social Characteristics
 

Of the thirty-one nuns identified at Sion, twenty-nine were patrician.

Contributors Notes
 

Sukopp beleived that Sion was a daughter-convent of the Cistercian house of Oberwesseling, but Steffen has refuted this contention.
