Site-specific works of art, meaning expressly created for the place where they are installed, punctuate the route, interacting in a harmonious or dialectical way with the chapels and the surrounding landscape. The installations, created by Italian and international artists, both renowned and emerging, form a poetic narrative open to different interpretations, enhancing the history and nature of the territory. Each year, a specific theme becomes the leitmotif that connects the installations and gives a new and distinctive perspective to the routes.
