The abbey suffered from the Turkish invasions of the 16th century, particularly in connection with the Siege of Vienna in 1526. Although forethought on the part of abbots saved many of the abbey's valuables by sending them for safekeeping elsewhere in advance of the incursions, the community was unable to escape the punishing taxes of the war period, and descended into poverty: one abbot was nearly arrested for failure to pay taxes. During the Reformation, another abbot absconded with the cashbox.
