The aim of this project is to add a new design to a historical site which is San Pietro Plaza in Rome. The Idea is to add Vertical mirrors between Columns to create illusion that visitors can see right through the piazza. Mirror panels alternated with columns to create vertical strips between the columns on each side of the columned corridor. Panels that thanks to a system of invisible Camouflage method project the view of Piazza on the floor of columned corridor and give a new experienced reflect view of other side the Piazza. The entire project is about light and shadow, reflected and projected light and change.
