Contrary to the Cistercian custom of only building monasteries in remote areas, an exception was made for King Frederick.
Frederick succeeded in freeing up the Dominican monastery next to his residence (founded by Leopold VI in 1227) for Cistercians from Rein Abbey.
[2] Emperor Frederick was imaginative when it came to the abbey's endowment: the fortress of Rohr near Wildon was confiscated as a rebel estate and donated to Neukloster.
[4] From 1797 to October 1803, the monastery served as a residence for the governor of Lombardy, Archduke Ferdinand Karl of Austria-Este, his wife Maria Beatrice d'Este and their children, after they had been exiled during the Coalition Wars.
The east façade towards the garden, the Chapel of the Holy Cross, and the baroque refectory with its frescoes by Johann Baptist Bergl were also restored and refurbished.
