North of Olomouc Castle, on the opposite left bank of the Morava River, lies a small rocky hill named Hradisko.

A Přemyslid castle (settlement) was originally built on the site in 1030, which had been the seat of prince Otto I of Olomouc, the youngest son of Bretislav I Duke of Bohemia.

The Benedictine monks were forced to leave Hradisko and found reception at the Opatovice nad Labem monastery (cs:Opatovický klášter) in east Bohemia.

This change may have been linked more broadly with the former trend when the Premonstratensians became a mainstay of religious reform and the papacy, and therefore their arrival in the Czech lands was accompanied by hostility towards the Benedictines.

The almost square floor plan, 100 × 115 metres, consisting of the four-winged building with a rectangular platform, with corner towers and a moat, was built on the foundations of the old monastery, and is divided by an inner lateral wing into two parts - the Convent and the Prelature.
