The Benedictine Abbey of Saint-Germain-des-Prés was the burial place of Merovingian kings of Neustria. The Abbey was founded in the 6th century by Childebert I, the son of Clovis I (ruled 511–558). Under royal patronage the Abbey became one of the richest in France; it housed an important scriptorium in the 11th century and remained a center of intellectual life in the French Catholic church until it was disbanded during the French Revolution.
The church was frequently plundered and set on fire by the Normans in the 9th century. It was rebuilt in 1014 and rededicated in 1163 by Pope Alexander III to Saint Germain of Paris, the canonized Bishop of Paris and Childeric"s chief counsellor. A new refectory was built for the monastery by Peter of Montereau in around 1239 - he was later the architect of the Sainte-Chapelle.
The abbey church"s west end tower was pierced by a portal, completed in the 12th century, which collapsed in 1604 and was replaced in 1606 by the present classicising portal, by Marcel Le Roy. Its choir, with its apsidal east end, provides an early example of flying buttresses. An explosion of saltpetre in storage levelled the Abbey and its cloisters, the statues in the portal were removed (illustration) and some destroyed, and in a fire in 1794 the library vanished in smoke.
Until the late 17th century, the Abbey owned most of the land in the Left Bank west of the current Boulevard Saint-Michel and had administrative autonomy in it, most clearly for the part outside the walls of Paris.
The tomb of philosopher René Descartes is located in one of the church"s side chapels.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.
