The Visconti Citadel of Piacenza is a fortification erected by the Visconti of Milan in the 14th century in Piacenza, Emilia-Romagna, northern Italy. In the 16th century, a new building (Palazzo Farnese) was planned and initiated on the Citadel's site but remained uncompleted. Therefore, about half of the Citadel was not destroyed and survived until today. Read more on Wikipedia
