Bellinzona commissioned the internationally famed installation artist Felice Varini to create a work to mark the inclusion of Bellinzona's fortifications in the renowned list of Unesco World Heritage Sites. Varini, who was born in Locarno in 1952, adorned San Michele Hill and the walls of Castelgrande with red stripes, which appeared to fall across the medieval fortress and the rock on which it stood as if projected from some distant point in the universe. The visual effect obtained was one of unity between the two. With amazingly simple means he achieved his aim which was to unite the spatial elements of building and nature, whilst producing an optical illusion of one-dimensional unity.
