The concept of our proposal is to create a strong and yet free line which separates the surface of Varvakeios square into two parts. The various levels created are organized with formatted triangulations that are passing as secondary alignments to the square level. Thereby the two axes of interests are integrated, the Athena Street and Theatre Street and form a close embrace. This gesture is compared with the imprint left by the phenomenon of the tide in its wake. Indeed in the central area of the square, beneath floating concrete slabs traces of water that entered the heart of its "cavity" can be found. The dynamic shape is completed by placing the flea market, linearly to the south in the form of a metal scaffold.
