The paper will present the contemporary practice of church architecture in Bulgarian, Romanian, Russian and Greek orthodox churches, at the end of the XX and the beginning of the XXI century, and analyse the relationship of traditional and contemporary elements, with the aim of determining main trends and development tendencies. Free development of sacred architecture was interrupted by long reigns of authorities opposed to Orthodox Christianity. After the downfall of Communist regimes, conditions were created for the unobstructed construction of sacred buildings in all Orthodox countries, while the issue of traditional church architecture re-emerged as important. Further development of Orthodox church architecture may be affected by some issues raised in relation to the structure and form of liturgy, regarding the internal organisation of the temple. The freedom of architectural creation is strongly supported by the richness of forms created throughout history. Traditionalist approaches to the architectural shaping of churches are dominant even nowadays, tradition being understood and interpreted individually. At the same time, efforts to introduce contemporary architectural expression into church architecture have been increasing and gaining strength.
