The Ducal Palace was the official and most significant residence of the Gonzaga Lords during their long rule. The guided tour of the present National Museum of Palazzo Ducale offers the visit of magnificent rooms, complex structures connected by corridors and galleries, squares, courtyards and several gardens. With more than 500 rooms it's among the most extensive aristocratic palaces in Europe. It houses masterpieces of the 15th and 16th centuries such as Mantegna's Bridal Chamber in the Castel of San Giorgio, the Hall of King Arthur's Knights by Pisanello, the Isabella d'Este Apartment with its precious cabinetry works in the Old Court, Raphael's complete cycle of woven Flemish tapestries, the Hall of Rivers close to a rare hanging garden, and the amazing Hall of Mirrors.
