Arezzo in Luce is a video mapping intervention that activates the facade of the Palazzo dei Priori as a large narrative device. Through a flow of moving images, the work traverses the history and identity of Arezzo, from its Etruscan origins to the Renaissance, to a symbolic and universal dimension. Light becomes a language capable of intertwining time, knowledge, and Christmas imagery, transforming architecture into an immersive and contemplative experience.
