[5] It was the largest and most impressive church in medieval Poland after Wawel Cathedral, and served as the Odrowąż family's burial place until the 16th century.

There is also the Polish Renaissance-style abbot's palace, built around 1569, as well as the red-brick monastery, with a broad inner courtyard, outbuildings, vegetable garden, greenhouse, etc.

[4] Under the reign of Henry I the Bearded, the Duke of Silesia, a community of monks was brought in from Lubiąż Abbey to Mogiła by Odrowąż around 1219, to commence the construction of the brand new church in his diocese.

The monastic community, consisting of the 13 professed monks mandatory for an independent monastery, moved in around 1225, although the expansion of the abbey continued for years to come.

[6] The Mogiła Abbey was confirmed by the Roman Curia through a papal bull signed by Pope Gregory IX on 9 June 1228.
