Jouarre Abbey was traditionally founded around 630 AD by the Abbess Theodochilde or Telchilde. She was inspired by the visit of St. Columban, the travelling Irish monk who inspired monastic institution-building in the early seventh century. As part of its Celtic heritage, Jouarre was established as a double community of monks as well as nuns, both under the rule of the abbess, who in 1225 was granted immunity from interference by the bishop of Meaux, answering only to the pope.
The Merovingian (pre-Romanesque) crypt beneath the Romanesque abbey church contains a number of burials in sarcophagi, notably that of Theodochilde's brother, Agilbert (died 680), carved with a tableau of the Last Judgment and Christ in Majesty, highlights of pre-Romanesque sculpture. In the mid-ninth century the abbey acquired relics of St. Potentian; the relics assembled at Jouarre attracted pilgrims. The reputation of the house stood so high the abbey received a visit from Pope Innocent II in 1131 and was able to house a synod in 1133. The abbess's submission to the bishop of Meaux did not come about until Bossuet held the post in 1690.
The abbey is an important pilgrimage center. A fortified town was built around it and gave birth to the present city of Jouarre.
At the time of the St. Bartholomew's Day massacre (1572), the abbess Charlotte of Bourbon (1547–1582) converted to Protestantism and escaped from the abbey in a cart of hay, and fled to Germany. She married William I of Orange-Nassau.
The present monastery buildings, once again occupied by Benedictine nuns, date from the eighteenth century; their traditional vegetable and fruit garden are notable.
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.
