This convent was founded circa 770 by the last Adilolfing duke, Tassilo III of Bavaria, as a Benedictine double house. The house later split into a convent for women and a monastery for men in different locations (Frauenchiemsee and Chiemsee).
Abbess Irmengard, daughter of Louis the German (Ludwig des Deutschen), grandson of Charlemagne (Karl der Grosse) served as the first abbess, dying here on July 16, 866.
The foundation began with a rich endowment, but encountered financial difficulties during the Succession War of 1504.
The church was destroyed in 1803.
The Staatsbibliothek in Munich contains two manuscripts from this house: #Cgm 845 and Clm 27442.

St. Irmengard: No Poor on the Isle of Chiemsee
In 1803 under guidelines for general secularization, the convent was dissolved and all its possessions were assumed by the Bavarian state. In 1836/8 the convent was refounded by Ludwig I of Bavaria under the condition that it run schools on both the Chiemsee islands.

After the canonization of S. Irmengard (Dec. 1928), this convent became a pilgrimage site for those wishing to visit her grave. The convent currently runs the Volksschule of both of the islands on the Chiemsee. http://www.bayern.de/HDBG/ks/ksstart.htm
