The monastery was plundered and set on fire by Ottoman troops during the 1529 Siege of Vienna and suffered further serious structural damage by the 1590 Neulengbach earthquake . Under Abbot Georg Fasel ( 1616-1631 ) an intensive rebuilding programme began , finishing in 1660 , during which the great majority of the present-day buildings were constructed . The chronicle of the charterhouse written by Abbot Leopold Brenner was available from as early as 1669 , but was not printed until 1725 . Brenner had lived here from 1641 and made his profession in 1650 , and was thus an eyewitness of the building of the early Baroque monastery . In 1683 renewed Turkish assaults during the Battle of Vienna caused more destruction , launching a further programme of repairs and refurbishment s which finished only in 1750 . <!--=== Building and decorative stone === Bei dieser Bautätigkeit wurden als Bau- und Dekorsteine verwendet : ''Flyschsandstein'' (historische Bezeichnung ''Wiener Sandstein, Schleifstein'') als Bruchstein, Mauerstein, Quader, Gewändesteine von Türen und Fenstern, Fußbodenplatten, Architekturteile, Wasserrinnen.
