The Palace of the Marquesses of Fronteira was built in 1671 as a hunting pavilion to Dom João de Mascarenhas, 1st Marquis of Fronteira, who received his title from King Afonso VI of Portugal for his loyalty to the House of Braganza in the Portuguese Restoration War.
The house and the garden have glazed tiles representing different themes such as battles or monkeys playing trumpets. The Room of the Battles has panels representing scenes of the Portuguese Restoration War; one of them shows D. João de Mascarenhas fighting a Spanish general. The dining room is decorated with portraits representing some members of the Portuguese nobility, painted by artists such as Domingos António de Sequeira.
The chapel, dating from the end of the 16th century, is the oldest part of the palace. The façade is adorned with stones, shells, broken glass and porcelains. It seems that those pieces were used during the palace’s inauguration and were broken on purpose just not to be used again.
In spite of being the current residence of the Marquis of Fronteira some of the rooms, the library and the garden are open to public visits.
The palace garden, an area of 5,5 hectare, is adorned with Portuguese tiles with pictures that represent the different arts as well as mythological figures. The garden hedges are cut in order to represent the different year seasons. There is also a stone staircase which leads to a wall line with busts of the Kings of Portugal.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.
