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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
