In the early fifteenth century, Franciscan Third Order Regular communities began to be established in Ireland. In 1445 the archdeacon of Connor was sent a mandate by Pope Eugenius VI, authorising him to establish a Franciscan Third Order Regular friary in his diocese.
A 1580 map of the County Antrim coastline shows the friary at ‘Glanarme’ on the other side of the river from the castle. It was probably closed by the beginning of the seventeenth century, but its site continued to be the favoured burial place of the local population, including settlers from Scotland.
Little of the friary survives today, and what remains is not easy to interpret. It was aligned along the traditional east-west axis, so what was once thought to have been the chancel is now believed to have been a transept.
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.
