The Ducal Palace of Mantua is a complex of buildings built over a long period – from the beginnings of the 14th all the way to the 17th century. During the latter period, the main ruling family of Mantua, the Gonzaga, experienced their decline. The complex is formed by about 500 rooms and covers a surface of almost 34.000 square meters. To create the palace, the most important artists of the various eras were called by the powerful Gonzaga family with the task to increase the magnificence of their residence. The more significant names are Bartolino da Novara, who projected and directed the construction of San Giorgio Castle, as well as Antonio Pisano, known as Pisanello, who realized a famous cycle of frescoes inspired by the legend of King Arthur, Andrea Mantegna, artist of the famous Camera Picta or "Chamber of the Newlyweds", and Giulio Romano, famous for both his paintings and the scenographic project of the architectural creations.
