[Abstract]The subject of this thesis are the semiotic aspects of the architectural graphics' history. It is suggested that the main expressive system in the architecture design - „architectural graphics“ is to be given a new meaning in the light of semiotics, as a contemporary science paradigm. The history of the architectural drawings is to be examined as a history of a system of signs, as a growth and development of an original architectural language. The aim of this paper is to prove the necessity and also to test the limits and the range of this research area. The study must altogether present the historical base of the architectural drawing systems and to analyze the concentration of graphics’ meanings, comparing to the contemporary elements in the design process. It shall also follow the existing ways of transferring architectural information, according to the audience, the culture and the building methods of the historical period. The study will focus over the communication processes in the architectural design, and will examine the key points of decoding and apprehending the architectural experience. The results of this study are expected in the fields of architectural history and education, same as in the area of visual and especially architectural semiotics. The value of this paper is to give a referance point for the future semiotics research over the architectural graphics, and another studies in the field of architectural semiotics.
