Château d'Arques-la-Bataille was originally a motte-and-bailey castle built to the steep hill around 1050. The castle was reconstruted in the 12th century. The long curtain wall and moat surrounded the Norman style donjon, a keep. The castle saw several battles and besieges during the centuries; the rebellion in 1052, Hundred Years' War and the most well-known in 1589 as part of the Wars of Religion. In 1688 the château was abandoned and later partially demolished and sold as the private property. Today the magnificent Château d'Arques-la-Bataille lies in ruins.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.
