The abbey suffered fire damage in 1220, 1275 and 1313, but narrowly escaped destruction at the hands of the invading Hungarians in the late 15th century and the marauding Turks in 1532, although they caused devastation in the surrounding area. Later in the 16th century the Reformation and the spread of Lutheranism caused more difficulties, a trend which only began to reverse from 1575 with the appointment of Abbot Georg Andreas (1575–1585) from Niederaltaich Abbey. The abbey also suffered damage during the Thirty Years' War.
