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:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
