The central square in Plovdiv marks a plethora of historical layers in a non-harmonious relation. One over another the layers are reclaiming their dominance over the square. The proposed design is using the language of one to expose the other and vice versa. The grid of the Forum of the ancient Philopoppolis is exposed on the surface in a repetitive regular form that is referring to the building legacy of the contemporary layer. Out of the regular grid arises a set of columns in two orthogonal axes, Cardo and Decumanus, thus marking every of the excavated sites. Their regularity in irregularity becomes a visual connection both present and absent in the image of the city. Columns appear as the sequence during the walk and culminate as a composition from one of Plovdiv’s high points.
