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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
