Historia budowlana późnoromańskiego kościoła w Tulcach koło Poznania w świetle badań architektonicznych

he aim of this paper is to present a structural history of the late Romanesque church in Tulce (district Poznan). Noninvasive architectural research of the building was conducted in 2014. Its results were then confronted with the literature on the subject. On this basis it was possible to identify structural changes since the moment the church was built until the 20 th century. The original church was made of brick in Monk bond and Gothic bond. It consisted of three parts: a squarely closed chancel, nave and extension in the western part – probably of the same size as the chancel. Comparative analysis enabled to date the church for around the half of the 13 th century. Later on, in the medieval period, it was reinforced with the buttresses and had the pinnacles rebuilt. The greatest alternations took place in the 18 th century. Partly Romanesque walls were then dismantled and the whole church was extended towards the west. Original windows were either bricked up or enlarged. The initial entrance was also bricked up and there was a tower established above the new part of the main frame. Regardless of the numerous changes, the original form was well preserved as well as the structure of the church, which allowed the reconstruction. Also the analysis of the walls made it possible to follow the 13 th century building process. Therefore, the monument possesses great authentic and historical values, especially in terms of recognition of medieval architecture in Greater Poland (Wielkopolska). This was the base for evaluating the elements from the later periods as they should be submitted to conservational protection as well as the initial structure.
