The Palazzo Ducale di Mantova ('Ducal Palace') is a group of buildings in Mantua, built between the 14th and the 17th century mainly by the noble family of Gonzaga as their royal residence in the capital of their Duchy. The buildings are connected by corridors and galleries and are enriched by inner courts and wide gardens. The complex includes some 500 rooms and occupies an area of c. 34,000 m². Although most famous for Mantegna's frescos in the Camera degli Sposi (Wedding Room), they have many other very significant architectural and painted elements.
The Gonzaga family lived in the palace from 1328 to 1707, when the dynasty died out. The oldest structures, those located on Piazza Sordello square, were built between the 13th century and the 14th century by the Bonacorsi family, who dominated Mantua before being ruled out by the Gonzagas in 1328.
In the late 14th century, an imposing fortress, the Castle of Saint George, was built near the city’s lakefront. The castle was designed by military architect Bartolino da Novara as a defensive structure aimed at protecting the heart of the town, and subsequently converted into the main residence of the Gonzaga family.
In 1556, Guglielmo Gonzaga took the decision to merge those buildings into a single, grandiose architectural complex. Therefore, a number of late Renaissance-style courtyards, gardens, passages, porticoes, and new wings were built in the second half of the 16th century after designs by some of the most renowned architects and artists of the time, including Giulio Romano, Giovan Battista Bertani, and Antonio Maria Viani.
Subsequently, the buildings saw a sharp decline, which was halted in the 20th century with a continuing process of restoration and the designation of the area as museum. In 1998, a hidden room was discovered by Palace scholars. The room is thought to have been used for performances of Monteverdi's music in the late 16th century.
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
