The Holy Spirit (Helgeand) Church, sometimes incorrectly mentioned as St. James, was built in the early 1200s. It was probably constructed as a chapel for the Danish Guild and donated by the Danish King Valdemar. In the mid-1200s the guild lost its importance and the church was sacrified as Holy Spirit Church and it also functioned as a sanctuary. The church is octagonal and built on two floors. Both floors have a common choir.
The original central tower collapsed around 1365 and Johannes van Wese donated 100 mark to the reconstruction. The church was was destroyed by fire in 1611. The church ruins are open to visitors in summer season.
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.
