The plan of cult buildings consists of two large zones: the altar (Latin: Presbutery), where the sacred ritual takes place, and the hall for parish. Initially, the layout of the cult building was simple: a single apse was created for the altar. In early basilics of Latin and Greek cross-design aisles never lasted around the altar and did not create sidewalks around the choir (Latin: Chorus), but in the course of development, the layout of the cult buildings and the altar changed: it started to arrange chapels as secondary preaching places. Changes in church architecture in Europe also influenced plans and structure of Catholic congregation's churches in German cities. The goal of the research: to analyze the plans and architectonic structure with the secondary preaching places of the Catholic congregation’s churches in cities of the Livonian and State of Teutonic Orders in the 13th–15th centuries created by the influence of the construction of cult buildings in German cities.
