One of the place i love more in the city is the SFORZA CASTLE (1360-1499),not only because you can meet the city history,not for the DUCAL COURT,THE ROCCHETTA a fortress inside the fortess considered unassailable by enemies during sieges.BONA OF SAVOY'S TOWER.You can see many interesting museums inside with masterpieces by LEONARDO DA VINCI in the service of LODOVICO IL MORO and archistar DONATO BRAMANTE made ofne of the most great RENAISSANCE center around.
