Seitenstetten lies in the Mostviertel in Lower Austria.

One Udalschalk or Udiskalk, first mentioned in 1109, founded a monastery there in 1112 and gave all of his properties in Seitenstetten, Grünbach, Heft and Stille (in today's Upper Austria).

In 1116, Bishop Ulrich I. von Passau, related to the Udalschalk family, consecrated the abbey's church and donated the large Aschbach parish.

Around 1180, Wichmann von Seeburg, Archbishop of Magdeburg, donated large woods near the Ybbs river.
