Trends in development of 1945-2015 sacral architecture in Poland are presented in the paper. The issue is analysed on the example of Czestochowa Archdiocese churches. The analyses are based on the authors’ own researches conducted between 2010-2015. Churches drafts, information about estimate year outlays and data from parish records were collected from each parish and considered. The author especially focuses on the buildings from the 70s,80s and 90s, which are not suited to the current needs of parishes. Visible trend to build very large sacral objects in the 70s/80s, due to uncertainty of getting further building permissions is described. Multifunctional buildings, containing catechetical classrooms erected as a result of restrictive government regulations on the construction of churches in the 80s and 90s are presented. The author emphasizes that in the XXI century, smaller and better adapted to the needs of the local community church buildings are created. These facilities are in addition more energy efficient and built with materials of better quality.
