The Gothic parish church of Środa Wielkopolska probably began to be built at the beginning of the 15th century. It can be assumed that the works were advanced or completed in 1411, when the Dominicans were brought to the town, who began to build their own temple and since the town also managed to erect the city walls. From 1419, regular congresses of the Greater Poland nobility, held in and around the church, began to take place in Środa. During the regional councils, the senators met inside the temple, the deputies stood in the stands in front of the church, and the secretary in the chapel, separated from irascible debaters with a metal grate. In 1423 the building was raised to the rank of a collegiate church. This promotion was to be ensured by a local priest named Bartłomiej.
At the turn of the 15th and 16th centuries, the collegiate church was enlarged by adding aisles and raising the tower. It is not known who was the initiator of this rebuilding. It could have been a local parish priest, town or staroste, since the right of patronage belonged in Środa to the king. The period of reconstruction coincided with the taking of the function of the staroste of Greater Poland (Wielkopolska) by Ambroży Pampowski, coming from a meaningless and poor family, but appointed by King Jan Olbracht due to the inefficiency of the aged Jan Ostrorog during the Tartar threat in 1498. This nomination was an insult to the old families of Górkowie, Szamotulscy and Ostroróg, who entered into fierce rivalry with Pampowski, perhaps also in the field of religious and artistic patronage.
In the mid-16th century, the tower was topped with a Renaissance attic, and in the years 1598-1602 a renaissance chapel of the Gostomski family was added from the south. The collegiate church was renovated and renewed in 1869, 1891-1892 and 1929-1932. In 1908, a fire destroyed the music choir and some of the equipment, while during World War II, the Germans robbed the 14th-century golden paten, chalice, candlesticks and twenty-one wooden figures from the turn of the 15th and 16th centuries. In addition, they damaged canonical oak stalls from the 16th century.
The parish church in Środa Wielkopolska was erected in the northern part of the medieval town, close to the city’s defensive walls. Originally, this building had one, rectangular nave and two-bay, also rectangular chancel. The above two bays were of varying sizes, covered with a cross-rib vault, while the nave was probably covered with a wooden ceiling. On the west side, on the axis of the facade, a four-sided tower was erected, reinforced with two corner buttresses placed at an angle. Its external façades were richly articulated with blind panels, and inside on its floor there was a gallery with a high arcade opened to the nave. On the north side of the presbytery there was an elongated, four-sided sacristy.
In the mid-15th century a small, square chapel was attached to the nave of the church from the south side, covered with a relatively simple, four-pointed stellar vault.
As a result of the late-Gothic reconstruction at the turn of the 15th and 16th centuries, the collegiate church, by adding two low aisles, became a basilica building, with a narrower, five-side ended presbytery, narrower than the central nave. The sacristy was still adjacent to it from the north, and the tower was from the west.
During the rebuilding, stellar vaults in the aisles and cross-ribbed vaults in the extended presbytery were built. The arcades leading to the aisles were cut directly into the mass of the walls. The individual bays of the added aisles corresponded to the dimensions of the fifteenth-century chapel, therefore, although it remained separate in the interior, it was absorbed in the external view by a block of the aisle and covered with a common roof, originally forming separate bipartite parts above each bay. To provide the interior of the aisles with adequate space, the lower parts of the former buttresses were partially removed. In this situation, the central nave could be too unstable to hold the vaults directly on its walls, so instead of external buttresses, huge wall pillars were erected, which, connected by high arcades, created support for the stellar vaults. On the faces of the pillars were placed pilaster strips on which ribs of the vault flowed.
