St Ibb's Church is located at the top of a hill in the churchyard. The oldest parts date back to the 13th century. It was enlarged in the early 1400s and vaulting was added later in the same century. The tower was damaged in wars between Sweden and Denmark and demolished in 1726. The font dates from the 13th century and is made of Norwegian stone. The altarpiece has been painted by Tobias Gemperlin before 1578 and donated by famous astronomer Tycho Brahe.
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.
