La Fondation Calvet is an art foundation in Avignon, named for Esprit Calvet, who left his collections and library to it in 1810. The foundation maintains several museums and a two libraries, with support from the town. The original legacies of paintings, archaeological items, coins and medals, and medieval sculpture have been added to by many other legacies, and a significant deposit of works of art from the Louvre. The archaeological collections and medieval sculpture are now housed separately in the 'Musée Lapidaire' - once the chapel of the Jesuit College. The main museum is in an 18th-century city mansion, to which modern buildings have been added; the Library bequeathed by Calvet, and the important collection of over 12,000 coins and medals, have moved to a different location in the city.
In Avignon there are six museums:
Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
