The first wooden church, founded by the Poznań bishop Jan Gerbicz, already existed at the end of the 13th century. In 1331 it burned down during the Teutonic Knights invasion. However, it continued to function in the following years. Around 1400, it was decided to rebuild, or actually build the current, brick building. It was carried out in several stages: first, a presbytery with a sacristy and a gallery was erected, while the presbytery had to function independently for some time, since it received a decorative western gable. After an unknown break, a nave was erected from the foundation of the Poznań bishop Andrzej Bniński, and finally vaults were established at the beginning of the 16th century.
In the eighteenth and nineteenth centuries church underwent numerous reconstructions. Its partial regothisation occurred in 1949-1958 under the direction of the architect Alexander Holas.
The church was built of bricks with the use of erratic stones in the pedestal, as an orientated, three-nave and hall building with a separate, older chancel of a rectangular shape. The outer façades of the presbytery were essentially smooth, articulated only with massive two-step buttresses, between which deep and very low descending windows with frames profiled with four fittings were pierced. Thanks to this, the massive wall manifested in the windows gained a counterweight in delicate details. The walls of the nave were made differently, more subtly and abundantly, although using the same fittings. At this point, slender windows almost do not cut into the wall, and a single and small step of the window frames of the nave shows that its walls are relatively thin (not counting the windows of the eastern and western facade of the nave).
The church was characterized by a large number of entrance portals. Small ogival portals were placed in the third bay of the southern and northern facade of the nave and in the western facade of the southern aisle. Their edges were revived only with concaves or chamfers. The three most important ones led to the western bay of the nave: from the west, south and north. The southern one was embedded in a small rectangular protrusion of the wall, the edges of which were framed by a shaft, and the archivolt was supported on a high, diagonally cut pedestal. The western and northern portals have the form of a tall and narrow ogival recess, in which lower, ogival passages, which were both profiled with a shaft, were placed.
Inside the church, nave was divided into four rectangular, transversely situated bays in the central nave and longitudinal in the aisles. Initially, the church was covered with a flat ceiling, only at the beginning of the 16th century it was replaced by a stellar vault, based on inter-nave arcades, as if cut out in the mass of a uniform wall and thus forming pillars with bases but without capitals. The large width of the arcades and their abundant profiling meant that the interior gained great spaciousness and uniformity, deepened by the high and deep ogival recesses of the walls of the aisles holding the windows. Both on the pillars and the walls between the recesses are led flat and relatively wide lesenes. It is characteristic that the vaults in the nave were laid carelessly, with crooked ribs, asymmetrically.
The two-bay presbytery received a slightly smaller width than the central nave. It was opened with an ogival arcade with a sharp profile, and lighting was provided by three Gothic windows located in the eastern bay. Originally, the light was also coming in through the high opening of the above-the-sacristy gallery, which was in the form of a high tower annex adjoining the choir’s western bay from the south. From the presbytery one could also get to the sacristy with a two-bay interior covered with a rib vault.
The church visible today has a Gothic appearance except for baroque gables, and is among the late Gothic monuments of the Greater Poland region one of the best preserved, largest and artistically perfect (despite the somewhat messy vaults). This appearance is the result of post-war regothisation, during which part of the original architectural details were carefully reproduced, some details distorted or blurred, and others were reproduced on the basis of probable guesses and individual fragments found (e.g. window shafts). The oldest movable relics are the Gothic baptismal fonts from the 14th and 15th centuries and the figure of Our Lady of Sorrows from around 1400.
