Saint-Jacques Flamboyant Gothic tower is all that remains of the former 16th-century Church of Saint-Jacques-de-la-Boucherie, which was demolished in 1797, during the French Revolution, leaving only the tower. What remains of the destroyed church of St. Jacques La Boucherie is now considered a national historic landmark.
The tower's rich decoration reflects the wealth of its patrons, the wholesale butchers of the nearby Les Halles market. The masons in charge were Jean de Felin, Julien Ménart and Jean de Revier. It was built in 1509 to 1523, during the reign of King Francis I. With a dedication to Saint James the Greater, the ancient church and its landmark tower welcomed pilgrims setting out on the road that led to Tours and headed for the way of St James, which led to the major pilgrimage destination of Santiago de Compostela.
A relic of the saint preserved in the church linked it the more strongly and in modern times occasioned its listing in 1998 as a World Heritage Site by UNESCO among the sites and structures marking the the pilgrimage routes in France that led like tributaries of a great stream headed towards Santiago in the northwest of Spain.
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.
