Following the proven system of the Germania Sacra , Hillen knowledgeably outlines the history, charter, spiritual and religious life, history of ownership, and especially, the personnel of the abbey from the time it was founded to its abolition in 1803. This adds another volume to Germania Sacra on the Cistercian Abbeys following St. Aegidii in Münster (3 rd installment 1), Marienfeld (3 rd installment 2) and Bredelar (3 rd installment 6).
