The Croatian international event "EARTH ELEVATION" led to "Matres Naturantis", a double installation in continuity with the path started in Croatia. Stone-shaped ceramic elements developed by the artists will carry writings and symbols aimed at the rebirth and protection of the Earth: a stone laid to found a new path of belonging, respect and wisdom. The same installation, created by two groups of artists in two places, Cava de 'Tirreni with the location at the "Villa Comunale" and Avigliana at the "Giardino delle Donne" of the Municipality itself, will ideally and physically be an expression of unity, remote sharing and comparison.
