Therefore, to create a bonding connection between people and the city, urban public spaces are the focal points which still need to be noticed more effectively by designers and managers. There are components which help the designers design more efficient urban public spaces and, as a consequence, there will be more vitality in cities. In today conditions, sustainability issues, as the solutions of having better future conditions, can considerably affect these components and give the society the opportunity of having more capable public spaces.

The aim of this paper is reviewing urban public spaces and sustainability notions and, as the result, reaching to some instructions for designing sustainable urban public spaces which have important impacts on these types of places. By doing this, not only the possibility of getting closer to the identity of cities, but also the necessary ground for the strong presence of sustainable urban public spaces in cities, are provided.
