Tavigny Castle dates to th late Middle Ages, and it may have been only a refuge tower that is now the central part of the castle. Its walls are long 10 meters, thick 2 meters and they had plenty of arrow slits. The lordship of Tavigny belonged at first to a family who wore already its name, but in 1360, it was already owned by the Ouren family, a powerful Middle-age family from the dutchy of Luxembourg. The central tower that was enclosed in walls with round towers in the corners got transformed little by little in a seignorial residence. The narrow windows and the arrow slits got substituted by large great picture windows and they made a very nice Louis XIII style ensemble
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.
