Villers Abbey (abbaye de Villers) is an ancient Cistercian abbey in Villers-la-Ville. In 1146, 12 Cistercian monks and three lay brothers from Clairvaux came to Villers in order to establish the abbey on land granted them by Gauthier de Marbais. After establishing several preliminary sites, work was finally undertaken in the 13th century to build the current site. The choir was constructed by 1217, the crypt by 1240, and the refectory by 1267. The church itself took 70 years to build and was completed by the end of the century.
During this period, the abbey reached the height of its fame and importance. Contemporary accounts suggest that roughly 100 monks and 300 lay brothers resided within its walls, although this is possibly an exaggeration. The lands attached to the abbey also expanded considerably, reaching some 100 km² of woods, fields, and pasturage.
Decline set in during the 16th century, tied to the larger troubles of the Low Countries. Spanish tercios, during the campaign of 1544, did considerable damage to the church and cloister, both of which were partially restored in 1587.
In the 17th and 18th centuries, the abbey's fortunes continued to diminish. The number of monks and the abbey's wealth dwindled, and it was finally abandoned in 1796 in the wake of the French Revolution.
The church, although in ruins, is an outstanding example of Cistercian architecture, with imposing vaulting, arches, and rose windows.
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.
