Present

The current Saint John the Apostle parish church is a three-aisled basilica with an elaborate two-tower western facade. The eastern part of the church is formed by a presbytery crowned with an apse and in the corresponding area underneath  there is a crypt, which can be reached by the renovated stairs from the southern aisle. This part of the church consists of Romanesque walls and a Gothic superstructure mostly visible in the external wall face. The western part is built of two chapels located in the lowest parts of the towers and an organ area including the organs. The entrance to the church is preceded by a vestibule. After the research and renovations in the 1970s the 18th-century format of the church was modified. The granite and brick wall of the earlier phases were exposed from under the plaster. The only plastered elements of the building remained the towers, the framing of the Baroque windows and arcade Gothic frieze on the face of the external wall of the apse. Parts of the interior wall face were also uncovered revealing a colourful mosaic and the structure of  subsequent building phases. What remained was the plaster from the ceilings, the rainbow arch and parts of the arcades between the aisles.

The church’s interior is mainly from the 16th to 18th century. It includes the architectural main altar built with columns and mirroring in its form the shape of the apse, marbleized side altars with the representations of Benedictine saints (Saint Benedict, Saint Scholastica) and a Rococo pulpit. The richly ornamented balustrade of the altar prospect was decorated with the Poraj crest, employed by  Abbot Andrzej Wilczyński – the founder of this part of the church’s interior. The interior is chronologically and ideologically crowned with a 1814 fresco by Jan Okrolniewicz from Gniezno. The prototype of the representation is an 18th-century painting  showing Bolesław the Generous above a simplified panoramic view of Mogilno.  At his feet putti present the view of the monastery and a list with the monks names . At the sides of the main picture there are scenes from the lives of the king and Saint Stanislaus.

 The monastery buildings have also been  renovated and modernised and currently the European Centre for Dialogue is located in its interiors. The garden, which can be accessed by the cloister, was also restored to its former glory. At its heart a Romanesque well was discovered during an archaeological dig.
