Reconstruction of archaeological buildings with destroyed or collapsed parts is considered oneof the most important and accurate operations in the field of preserving those buildings, given the continuityof these operations in the continuity of those archaeological buildings with their architectural and technicaldetails, and even their continued performance in their urban environment in many cases. These operationsare concerned with missing parts or the replacement of damaged parts. Many studies emerged that dealtwith this important aspect of reconfiguring and completing the demolished parts in historical and heritagebuildings, whether at the level of the part or all according to specific laws, but no study of the formal andintellectual mechanisms used to rebuild and reconstruct these buildings and their potential for architecturalproductions. Therefore, the research problem that emerged from the lack of clarity of knowledge about themost important formal and intellectual mechanisms for rebuilding in architecture and its cognitive indicatorswithin the outcome emerged, and the research was divided into two parts, the first part represented by thegeneral theoretical presentation that included the reconstruction processes and related determinants andclarification of the mechanism of formalism (similar and its connections) Theory and intellectual mechanism(analogy and its theoretical correlations), previous studies and the second part which represented the appliedside to form the theoretical framework from the above and applied it to groups of architectural productionsand then presented and discussed and analyzed the results of that application up to the presentation ofCrowns and recommendations that were referring to the general vision of the basic concept of researchadopted, the mechanistic aspect of form rather than intellectual.
