Resume. The manual is devoted to codes and signs in architecture, although it does not discuss them from the earliest period, but focuses on operating systems, presenting their historical antecedents and giving way to descriptions of their importance. The topic of codes and signs is well covered in the world literature, the abundant material available to the authors led to the writing of this textbook for the Georgian public, which is the first modest attempt to cover this issue in Georgian literature as a separate book.

The textbook is intended for students of Master’s and related specialties of the Faculty of Architecture, Urban Planning and Design of GTU, acting architects, art critics, those interested in the theory of Modern architecture, and a wide circle of readers.
