The Palace of Charles V is a Renaissance building located on the top of the hill of the Assabica, inside the Nasrid fortification of the Alhambra. The building has never been a home to a monarch and stood roofless until 1957.
The structure was commanded by Charles V, Holy Roman Emperor, who wished to establish his residence close to the Alhambra palaces. Although the Catholic Monarchs had already altered some rooms of the Alhambra after the conquest of the city in 1492, Charles V intended to construct a permanent residence befitting an emperor. The project was given to Pedro Machuca, an architect whose biography and influences are poorly understood. At the time, Spanish architecture was immersed in the Plateresque style, still with traces of Gothic origin. Machuca built a palace corresponding stylistically to Mannerism, a mode still in its infancy in Italy. The exterior of the building uses a typically Renaissance combination of rustication on the lower level and ashlar on the upper. Even if accounts that place Machuca in the atelier of Michelangelo are accepted, at the time of the construction of the palace in 1527, the latter had yet to design the majority of his architectural works.
The plan of the palace is a 17-metre high, 63-metre square containing an inner circular patio. This has no precedent in Renaissance architecture, and places the building in the avant-garde of its time. The palace has two floors (not counting mezzanine floors). The classical orders are in pilaster form except around the central doorways. On the exterior, the lower floor is in the Tuscan order, with the pilasters 'blocked' by continuing the heavy rustication across them, while the upper storey uses the Ionic order, with elaborately pedimented lower windows below round windows. Both main façades emphasize the portals, made of stone from the Sierra Elvira.
The circular patio has also two levels. The lower consists of a Doric colonnade of conglomerate stone, with an orthodox classical entablature formed of triglyphs and metopes. The upper floor is formed by a stylized Ionic colonnade whose entablature has no decoration. This organisation of the patio shows a deep knowledge of Roman architecture, and would be framed in pure Renaissance style but for its curved shape, which surprises the visitor entering from the main façades. The interior spaces and the staircases are also governed by the combination of square and circle. Similar aesthetic devices would be developed in the following decades under the classification of Mannerism.References:
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.
