The second monastery, which was consecrated to Our Lady was founded 1132 by the Counts of Dießen.
In 1150 the Counts gifted their manor to the new monastery.

In 1157, the Counts of Dießen bequeathed to the monastery all their possessions in and around Dießen with all serfs, fish rights and forests.
The castle of the Counts went to the monastery too, but with the order to demolish it.

While the monastery shortly held the jurisdiction over the town of Dießen, by 1326 the free market won all its rights back.
This led to the existence of two clearly separated legal areas in the town.
Although the monastery lost jurisdiction over the market around 80 estates were still allodial to the monastery.

The jurisdiction area of the Augustiner-Chorherrenstift itself included Raisting, Lachen, Bierdorf, Engenried, St. Alban, Riederau, Rieden, St. Georgen, Wengen, Bischofsried and Pitzeshofen.

In the years 1632 and 1634, the monastery was looted by the Swedes, 1704 by troops of the emperor.

In 1673 under Provost Renatus Sunday an extension or partial rebuilding of the monastery took place.
Under Provost Herkulan Karg the new monastery church was finished in 1739.

The monastery was dissolved in 1803 during the secularization in Bavaria.
Most of the Abbey's possessions were sold to private citizens, only the vast forest was transferred to the state.
At the time of the dissolution, 18 convent lords and 5 lay brothers lived in the monastery.

In 1917, nuns from Augsburg acquired the surviving convent buildings and operated their mother house there until 1968.
In 2014, the monastery was abandoned by the last nuns.

Since 2018 the buildings of the Abbey house a psychosomatic clinic.
