Ardenne is the third largest abbey in Caen region. It was founded in 1121 by a small Christian community. During the 1789 Revolution, the religious community was expelled from Ardenne Abbey, the building's original purpose was modified and it was stripped of the furniture and works of art which had been collected.
On 7 June 1944, the second day of Normandy Invasion, the Germans took Canadian soldiers prisoner and escorted them to the abbey where eighteen of them were executed, in contempt of the Geneva Convention and prisoners’ rights. Other summary executions took place during this month of fighting. The abbey was taken back from the Germans on 8 July 1944. Today, a memorial at the site commemorates this tragic event. In 1994, on the initiative of the Regional Council, a first wave of restoration and development works were launched at the farinier, the stables, Bayeux gate and the main building.
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.
