The abbey of our Lady of Bonport was founded in 1189 by Richard the Lionheart, King of England and Duke of Normandy. According to legend, the King was in peril on the river Seine and made a vow that if he arrived safely (in French à Bonport) on the other bank of the river, he would found a monastery on that side. The abbey was built shortly afterwards with the help of local lords and was damaged and restored several times throughout history. Its closter and church were destroyed after Revolution. It is one of the few remaining cistercian abbeys in Normandy with monastic buildings of the Middle Ages including a magnificent 13th century vaulted refectory.
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.
