The Villa di Castello, in the hills near Florence, Tuscany, central Italy, was the country residence of Cosimo I de' Medici, Grand Duke of Tuscany (1519-1574). The gardens, filled with fountains, statuary, and a grotto, became famous throughout Europe. The villa also housed some of the great art treasures of Florence, including Sandro Botticelli's Renaissance masterpieces The Birth of Venus and Primavera.
