Boneffe Abbey was a Cistercian monastery on the banks of the Mehaigne in what is now the municipality of Éghezée. The abbot's residence, first built in the early 16th century and repaired in the 17th and 18th centuries, is now a listed building that is currently in use as a farmhouse.
The earliest attestation to the monastery's existence is a papal bull of 1222. The abbey church was consecrated in 1267. At this period it was a monastery for Cistercian nuns.
In 1413 the community of nuns was disbanded, and by 1461 the Cistercian Order had redesignated the property as a monastery for monks. The house was briefly evacuated in 1480-1483 due to an outbreak of plague. In November 1568, early in the Dutch Revolt, the abbey and its church were set on fire by rebel forces. The community fled and the abbot, Cornelis Lievens, died in Leuven in 1569. Rebuilding began in 1589, and the church was reconsecrated in 1617 by Jean Dauvin, bishop of Namur.
The monastery was on the front lines of the War of the Spanish Succession, just a few miles from Ramillies, and suffered depredations and damage accordingly. Fresh rebuilding work was completed in 1711.
After the French invasion of the Southern Netherlands, the revolutionaries suppressed Boneffe Abbey along with all other religious houses.
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.
