Summary Conceptual art is considered to be one of the branches of postmodern art and as its name suggests, concepts and thought are the main principles of this art. It is also one of the most fascinating and exciting arts of the 20th century, which questions all the rules and regulations of art and how the artistic process works and disrupts the common and stable infrastructure of art. Therefore, this change is remarkable in the process of experiencing and reading the work of art, just as a classical or modern work goes through the process of aesthetic experience for the viewer, the conceptual work carries its own experience. Conceptual art, like classical and modern art, has its own structure in its construction, and this structure affects its experience by the audience. In conceptual art, although it does not carry a visual aesthetic effect, it carries a mental form in its structure, so the perception of this form becomes an aesthetic pleasure for the viewer. Therefore, aesthetic experience is not unrelated to this type of art, even if it does not carry any visual aesthetic effects, decoration and organization in appearance as a ready-made object when displayed in an art exhibition.
