Palazzo del Monte di Pietà was built in 1616 for the Arciconfraternita degli Azzurri. The building was modified in 1741 with the addition of a first floor, a bell tower and a staircase. These were built to designs of the architect Antonino Basile. A fountain decorated with a statue of Abundance was built in the middle of the staircase.
The structure was damaged during the earthquake of 1783 and that of 1908. The building's upper floor was largely destroyed during the latter earthquake. The structure was further damaged by World War II bombings. Restoration of the building began in 1979, and it is now used for cultural purposes.
The Palazzo del Monte di Pietà is built in the Mannerist style. The ground floor has a central rusticated portal topped by a broken pediment, flanked by two windows on each side. The windows are topped by triangular pediments, and they are separated by niches.
The first floor of the building, which was constructed in the 18th century, had an open balcony flanked by two windows on each side. The balcony and the lower parts of the windows can still be seen, but the rest of the floor was destroyed in the 1908 earthquake.
The building contains a large vaulted hall which opens into a courtyard. This leads to the 18th-century monumental staircase, leading to the Church of Santa Maria della Pietà. Only part of the façade of the church has survived; the building itself was destroyed during the 1908 earthquake.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.
