The construction of Château de Conches-en-Ouche started in 1034 by Roger I of Tosny. The castle was captured by Philip II of France in 1199 and again by the English during the Hundred Years' War in 1364. It was recaptured by Bertrand du Guesclin in 1371. The castle was lost again in 1420, retaken in 1440, lost once more in 1441 before being finally taken by the French in 1449. In 1591, members of the Catholic League took refuge there; a potential base for enemies of the monarchy, it was demolished afterwards. The castle was classified as a monument historique in 1886.
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.
