Bordering comuni include Arezzo, Pieve Santo Stefano and Subbiano. It is one of I Borghi più belli d'Italia. The Battle of Anghiari took place on 29 June 1440 between the Republic of Florence and the Duchy of Milan. The battle inspired a Leonardo da Vinci fresco designed for Florence's Palazzo Vecchio known as the Lost Leonardo; current scholarship holds that the work was never completed. It is known from da Vinci drafts and a sketch of it by Peter Paul Rubens now in the Louvre.
