Built before the year 1000, the convent of Bosco ai Frati is one of the oldest in Tuscany. It passed onto the Franciscans in 1212. It was rebuilt in the first half of the 1400s by Michelozzo upon the order of Cosimo Il Vecchio dei Medici, who owned the nearby castles of Cafaggiolo and Trebbio.
The architect melted the charecteristics of the Renaissance style with the traditions of the medieval architecture. He included ribbing, vaults and frames in the choir inspired to the late-gothic style, while the cloister, dining hall and in the nuns' cells are distinctly Renaissance.
Many were the precious gifts left by the first Medici to the convent, like the precious wooden crucifix attributed to Donatello, today preserved in the small museum of sacred art attached to the convent.
The small museum was inaugurated in the 1970s when a room in the convent was selected to protect the convent’s most precious objects from theft and looting. One of them is the Christ by Donatello. The eminent sculptor has shown Christ just after his death, with his eyes half closed and the pupils fixed. The skinny and nude figure clearly shows the signs of beating.
