The monastery at Scheyern was established in 1119 as the final site of the community originally founded in around 1077 at Bayrischzell by Countess Haziga of Aragon, wife of Otto II, Count of Scheyern, the ancestors of the Wittelsbachs. The first monks were from Hirsau Abbey, of which the new monastery was a priory, founded as it was against the background of the Investiture Controversy and the Hirsau Reforms. The original site proved unsuitable for a number of reasons, including difficulties with water supply, and the monastery moved in 1087 to Fischbachau. When that site too proved unsuitable, they moved to Petersberg, in 1104.
