In page Leopold II, Margrave of Austria:

"

While Bishop Altmann of Passau stayed in Austria, the margraviate obtained a leading position in promoting the Gregorian Reforms, overruling the concept of proprietary churches and marriages of priests. Altmann introduced the Cluniac oberservance to Kremsmünster Abbey and in 1083 established the Augustinian monastery of Göttweig near Krems. In 1089 Margrave Leopold helped pay for the construction of Melk Abbey in the Wachau region by donating extended premises high above the shore of the Danube for the new monastery. The ruins of Gars am Kamp castle, the last margravial residence of Leopold, are 68 kilometres (42 mi) away.[1]
