Burtscheid abbey was founded in 997 under Emperor Otto III. The first abbot, Gregor, who came to Burtscheid from Calabria, is sometimes said to have been the brother of Theophanu, Byzantine mother of the Emperor. He was buried beneath the altar after his death in 999, and his date of death, 4 November, was kept as a feast day until the dissolution of the abbey.
In 1018 the Emperor Henry II endowed it with the surrounding territory. Also at about this time the monastery was raised to the status of an abbey, and the dedication was changed from Saints Nicholas and Apollinaris to Saints John the Baptist and Nicholas.
In 1138, the abbey was made reichsfrei by Conrad III, being granted Imperial immediacy, the privilege of being subject only to the Holy Roman Emperor, rather than to an intermediate lord. The abbey was under the Vogtei (loosely 'protectorship') of the Barony of Mérode until the abbey purchased its Vogtei from them, in 1649.
In 1220, under Emperor Frederick II and his chancellor, Archbishop Engelbert of Cologne, the Benedictines were evicted and replaced by Cistercian nuns who had previously been living at the Salvatorberg in Aachen, to whom the abbey's possessions were transferred. At the same time the abbey's reichsfreiheit was confirmed.
The abbey church was rebuilt in the mid-14th century, and again between 1735 and 1754 by the architect J.J. Couven.
In 1779, despite the refusal of permission by the council of Aachen, who by that time were responsible for local government in Burtscheid, the then abbess introduced a gambling house, and the street is still known today as Krugenofen Kasinostrasse.
Burtscheid was occupied by French troops in December 1792, and from September 1794 until 1804. They used the abbey church for the manufacture of balloons. In August 1802 the nunnery was secularised and dissolved.
The remaining abbey buildings are now used by a school and for residential and administrative purposes.
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.
