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:
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
