La Lucerne Abbey (Abbaye Sainte-Trinité de La Lucerne) was founded in 1143 by Hasculf de Subligny, son of Othoerne, the tutor of William Adelin, both of whom perished in the White Ship disaster of 1120, and later had the support of the English crown. The new monastery was settled from Dommartin Abbey near Hesdin. The foundation stone of the permanent buildings was laid in 1164 by Achard of St. Victor, who was later buried here. Construction lasted from 1164 to 1178 and was in the Romanesque style, in the restrained and sober manner of Cistercian architecture, except that the complex was dominated by an Anglo-Norman Gothic tower. Major structural renovations were carried out in the 15th and 17th centuries.
La Lucerne was the mother-house of four other Premonstratensian monasteries: Ardenne Abbey, Mondaye Abbey and Belle-Étoile Abbey (at Cerisy-Belle-Étoile) in Normandy, and Beauport Abbey in Brittany.
During the French Revolution, in 1792, the abbey was suppressed. Its buildings were at first turned into a cotton mill and then used as a source of stone.
In 1959, under the aegis of Abbé Marcel Lelégard (1925-94), the enormous task was begun, which still continues under the 'Fondation Abbaye de La Lucerne d'Outremer', of the restoration of the abbey. The first phase of the work was the reconstruction of the abbey church, particularly the ogival crossing vaults and the west front with its Romanesque portal, continuing to the refectory and cellars.
Work has continued since then and the tithe barn, the Romanesque lavatorium (the only one in Normandy), the medieval gatehouse (with its bakery and courtrooms), the dovecote, the park, the 18th century abbot's lodgings and the ponds are all now restored . The chapel of Blessed Achard is in the process of restoration.
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.
