The Château de Blain was originally constructed by order of Alan IV, Duke of Brittany, around 1108. The fortress passed by marriage to the Clisson family in 1225. Following Olivier I de Clisson's revolt against the Duke, the castle was razed in 1260.
Olivier I's son, Olivier II obtained permission from the Duke to rebuild the castle. The Clissons progressively enlarged the castle during the 14th century. In 1407, the castle became the property of the House of Rohan. Louis, duc de Rohan is buried here. During the French Wars of Religion, the castle was besieged and set on fire in 1591 during the fighting between the Duke of Mercœur and Jean de Montauban, the knight De Goust. It was restored by Catherine de Parthenay, who installed herself there with her children. In 1628, Henri II de Rohan having become the leader of the Protestant princes, Cardinal Richelieu ordered the dismantling of the castle which thus lost its military role.
The castle suffered further serious damage during the French Revolution. It was pillaged and burnt, along with the Rohan family archives. It served as a barracks and later as a prison. It passed through the hands of several proprietors, including Marie Bonaparte in 1918. These owners remodelled the north wing (known as the Logis du Roy) and the Mill Tower (la tour du moulin).
The South West Tower and the Drawbridge Tower with the buildings on either side form the entrance to the castle. Along with the Constable's Tower (tour du Connétable), the two towers in the south east and the monumental entrance on the south facade of the logis du Roi, they date from before the 17th century. Together with the remains of the towers and the fortifications linking them, these have been classified as a monument historique by the French Ministry of Culture. The north wing of the logis du Roi was remodelled in the 19th century. The castle is home to a fresco centre and an ancient printshop. It has been listed since 1977 as a monument historique by the French Ministry of Culture.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.
