The Hilleshög Church is a mostly Romanesque edifice, built in granite and brick, with some parts from the 17th and 18th centuries and later additions. It was probably built in the late 1100s and the sacristy and the porch were added in the 15th century.
Many of the paintings in the interior, dating back to the end of 13th century and they early 15th century, were painted over in the 18th century but were restored in the 1920s and in 2002, together with some of the furniture.
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.
