Guise castle is a medieval fortification in the town of Guise, in northern France. Originally an early medieval wooden motte and bailey castle, it was rebuilt in stone and then massively expanded during the 12th-16th centuries. It was remodelled by Marquis de Vauban in the late 17th century to meet the advances in sIege technology then taking place. Much of the castle was reduced to rubble during the First World War and, from 1952 onwards, it has been undergoing restoration by the Club du Vieux Manoir. Nowadays it is a popular tourist site.
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.
