The Château de Meung-sur-Loire, located next to the collegial church, was the country residence of the Bishops of Orléans. It was built and destroyed several times. The oldest still existing parts date from the 13th century and were built by Manassès de Seignelay (bishop from 1207 to 1221). Still standing are the main rectangular plan building, flanked by three towers, a fourth having been destroyed.
During the Hundred Years' War, the building was transformed into a fortress; it was taken from the English by Joan of Arc on 14 June 1429. At the end of the 15th century and start of the 16th century, building to the north incorporated a tower with drawbridge. The castle was abandoned from the Wars of Religion until the start of the 18th century, when Bishop Fleuriau d'Armenonville undertook the transformation of the structure into a comfortable residence.The rear façade was rebuilt in the Classical style by d'Armenonville. Beneath the castle are dungeons, a chapel and various medieval torture instruments, including one used for water torture.
In the middle of the 18th century, a wing was added to the southeast with a staircase serving the upper floors of the wing. In 1784, the chapel was built in the Neoclassical style, with sculpture by Delaistre. The two pavilions in the grounds are contemporary with this chapel.
References: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.
