From 10 September until the end of Expo 2015 Milan pays tribute to Leonardo da Vinci with 24 mini-exhibitions of the Codex Atlanticus, which contains the largest collection of drawings, sketches and writings by the Renaissance genius exploring his insights and ideas on a vast range of subjects including anatomy, geometry, mathematics, flying, botany, astronomy, architecture and weaponry.

Every year there will be four three-month exhibitions, which will be displayed either in the Sala Federiciana of the Biblioteca Ambrosiana, which has housed the code since 1637, or at the Sagrestia del Bramante in the church of S. Maria delle Grazie, the site of Leonardo
