A good design of public urban spaces considers all the visual and aesthetic determinants dedicated to its formation. In a design of public urban spaces in European cities, it is a studying perception of form in the townscape. In addition, most design focuses on the details of constituent elements to suit the overall consideration to aesthetic form. It has a lack of design study in the Arab cities, where all the considerations are not fully applied. The design neglects the study of the visual dimensions and the cultural identity of the Arab city. Therefore, this research is to fill the knowledge gaps and deficiencies about the formation of the urban spaces in Arab cities. The Methodology of this research is descriptive and analytic. It discusses the design determinants of visual and aesthetic composition of public spaces in the Arab cities. It is also a study on the determinants of visual reading of its components by analyzing their forms and their relationship with the surrounding elements (building masses, street furniture elements) and by using the space syntax assessment technique to identify the foundations and visual access to a graphic and aesthetic design reflecting the Arabic identity.
