Have you ever wondered if there is contemporary art around you? We will discover it together before entering the designated exhibition spaces. Activating a conscious gaze is the spark for curiosity. Training ourselves to capture stimuli, which we usually ignore, will be our guiding star. Siena has always been a territory of open-air art, but there are also hidden traces. How many will we find? Will they be definable as art? Why should an artist invade public space without leaving any trace linked to their signature? Is authorship in art always declared? Must the work be tangible? During a walk that will begin outside the Palazzo delle Papesse, we will let ourselves be guided by the hidden signs that each of us might catch, like a kind of Dadaist walk, at the end of which we will question what art is and how we can recognize it.
