The Abbey of the Santo Spirito (Holy Spirit), built by the Norman Count Ruggero and his wife Queen Adelasia in 1092–1098, was consecrated in 1153. It has been greatly altered in subsequent centuries. The original outlines are still identifiable to the rear, where its characteristic massive jutting apses can be seen. These are separated by flat pilasters and connected by a series of small arches. The left-hand entrance has an ogival portal from the 13th century. The lunette once contained a figure of Christ Blessing, which was eventually moved inside the Abbey. Notable are the rectangular nave and wooden-beamed ceiling. The walls and the apses have frescoes attributed to the 14th century. The vault of the apse shows a 17th-century figure of Christ Pantocrator.
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.
