Rottenbuch Abbey was founded as an Augustinian monastery in 1073 on land granted by Duke Welf I of Bavaria. The Abbey church was constructed between 1085 and 1125 in the Romanesque style. The design of a crossing transept and free-standing tower is unusual for a Bavarian church. Rottenbuch was a center of papal loyalty during the Investiture Controversy. Under the patronage of Emperor Louis the Bavarian in the 14th century, together with its location on the pilgrimage route to Italy, Rottenbuch became the most influential house of Canons Regular in Germany.
In the 18th century the medieval interior of the church was redecorated in the ornate High Baroque style by painter Matthäus Günther and stuccoist Josef Schmuzer. With the secularization of the Bavarian monasteries under Montgelas in 1803 the monastic buildings were pulled down and the noteworthy library sent to a paper mill; the Abbey church became a parish church, which it remains to this day.
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.
