Romania, placed at the crossroads of so many cultural vectors, is the keeper of a religious cultural  fund of great variety that covers an extended temporal area. Without the fear of being wrong, it may be said that Romania represents, at a small scale, the whole variety and tradition of Europe. The volume includes the materials of the 6^th edition of the Conference Series on Theoretical and Practical Issues on Built Heritage Conservation – TUSNAD, having as topic the Ecclesiastical Built Heritage Conservation. The texts of this publication were edited in four languages, in the idea of the Transylvanian multiculturalism.
