Keizersberg Abbey, also known as Mont César Abbey is a Benedictine monastery. The Keizersberg (Caesar's or Emperor's hill) was the site of the castle around which the city of Leuven grew up, and which local legend connected with Julius Caesar. The castle was demolished in 1782 by order of Emperor Joseph II. On the east side of the same hill a commandery of the Knights Templars was built in 1187, which when the order was abolished came to the Knights Hospitallers in 1312. This was secularised by the French in 1798, when the church and larger buildings were demolished.
A Benedictine house of studies was established in Leuven in 1888 by nine monks from Maredsous Abbey, and land was acquired on the present site in the following year for the construction of a larger establishment, in which the remains of the old commandery were incorporated. The first major conventual block, the north wing, was completed in 1897. The abbey was formally founded on 13 April 1899 as part of the Beuron Congregation, under the first abbot, Dom Robertus de Kerchove.
In 1914 the buildings were severely damaged by fire, and the monks took refuge in another Beuronese house, Maria Laach Abbey in the Rhineland, until after the end of the war, when reconstruction was possible. The abbey again suffered damage in World War II with the bombing of the buildings during air raids on Leuven in 1944, which among other things destroyed the last remains of the older buildings from the time of the Hospitallers, and the monastery was temporarily uninhabitable. By 1948 it was sufficiently restored to be able to set up a small community at Wavreumont in Stavelot, which was formally established as St. Remaclus' Priory on 21 June 1952.
When the French section of the Catholic University of Leuven was moved out of Leuven it was decided that the abbey should become a Flemish institution, whence the change from Mont César to Keizersberg. On 10 June 1968 the abbey was transferred to the Flemish Province of the Subiaco Congregation. The abbot and prior resigned in the same year, and a temporary administrator was appointed.
In 1969 part of the renovated abbey was converted for use as student accommodation, and is still used for that purpose.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
