In our country at the last decade has become a lot of reason for the renovations of public urban spaces and more specifically of the squares. Particularly because of a series of architectural competitions for the re-designation of central squares in Athens there was developed intense debate and criticism for the proposals of architects and for the final configurations. In this dialogue participated architects, citizens, journalists and organizations that implemented the projects. The views were expressed in articles in the press and in articles and reviews on various websites. Views that caused tensions, misunderstandings and disagreements about the role of the square. The existence of green,for an important piece of common opinion, was the measure for the acceptance of the renovations. So, the architectural designation didn’t seem to create good or bad, successful or problematic squares but only <> or <> squares.

The views and the comments that were published in the press and referred to the configuration of squares in Athens but also views generally about the public urban space and green in Greece were the primal material of the research.

In the first part of this work is analyzed the importance of public urban space and more specifically of square in the western world as well as in newer Greece. In this problematic frame of Greek public urban space is also placed the subject of green. Examining the parameters of this issue results contradictions of behaviours and mentalities that are also argued in the examples that follow in the second part of this work. It is about four examples of configurations of Greek squares of (Omonoia, Kolonaki, Syntagma and Monastiraki). In these are presented the architectural proposals, the public dialogue that was developed around them as well as the criticism abouttheir relation with the green.
