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 Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
