In several stages between 1651 and 1701, a Jesuit church was erected in Poznań. The construction was carried out by Tomasso Poncino, Bartłomiej Nataniel Wąsowski and Giovanni Catenazzi. The long construction time was the result of technical mistake made by Poncino at the beginning (between 1651 and 1653) and subsequent attempts to overcome them by his successors. The inviting final interior solution was obtained by fortuity. The powerful columns, that determine the nature of the interior, are a remnant of a plan by Wąsowski, to cover the nave with a barrel vault. Lack of technical knowledge prevented the placing of transverse arches and as a result the initial concept was abandoned (1675–1687). Instead of the vault, its wooden imitation was laid. Lonely columns became the starting point for creating an original arrangement. This concept was taken over by Catenazzi during the implementation of the further part of the church (1696–1701).Poznanjska jezuitska cerkev je bila zgrajena v več fazah med letoma 1651 in 1701 po načrtih arhitektov Tomassa Poncina, Bartłomieja Nataniela Wąsowskega in Giovan- nija Catenazzija. Gradnja se je močno zavlekla zaradi Poncinoviih začetnih tehničnih napak (med letoma 1651 in 1653) in poskusov njegovih naslednikov, da bi jih odpravili. Zanimiva končna rešitev notranjščine cer- kve je splet naključij. Mogočni stebri naj bi po prvotnem načrtu Wąsowskega podpirali obok s prečnimi loki, ki ga zaradi pomanjanja tehnološkega znanja nad tako široko ladijo niso uresničili; ladja je pokrita z lesenim stropom, ki posnema banjasti obok. Stebri, postavljeni za nerealizirani obok, so ostali in dali notranjščini edin- stven karakter. Zamisel o stebrih je predstavljala izhodi- šče za nadaljno gradnjo, ki jo je med leta 1696 prevzel in do leta 1701 zaključil Catenazzi
