The Church and Dominican Convent of Santa Maria delle Grazie in Milan with "The Last Supper" by Leonardo da Vinci represent architectural and painting styles of the Renaissance period of the 15th century. The towns of Mantua and Sabbioneta are also listed as a combined World Heritage site relating to this period, here focussing more on town planning aspects of the time than on architectural detail. While Mantua was rebuilt in the 15th and 16th centuries according to Renaissance principles, Sabbioneta was planned as a new town in the 16th century.
