The town of Foix probably owes its origin to an oratory founded by Charlemagne, which afterwards became the Abbey of Saint Volusianus in 849.

The castle, whose foundations date back to the early tenth century, was a strong fortress that withstood the repeated attacks of Simon de Montfort IV between 1211 and 1217, during the Albigensian Crusade.

In accordance with the General Code of Territorial Collectives - Article L2121-2, the number of council members is fixed in relation to the size of the population.

The coat of arms used by the commune has the blazon D'or à trois pals de gueules (gold with three red bars).

In 1955 the post office issued a postage stamp with a face value of 50 cents, coloured black, green, yellow and red representing the Arms of County of Foix, reference YT 1044.

In 1958, the post office issued a postage stamp with a face value of 15 f., coloured ultramarine, grey, brown and green representing the Château de Foix, reference YT 11759.

It occupies the wide central reservation of the main thoroughfare, the Allées de Vilotte, the neighbouring Halle aux Grains, and has a mainly organic produce section a couple of hundred yards away, at the Square of Saint-Volusien, where there is a smaller covered market.

[7] Foix is twinned with the following places: These playing fields comprise 3 football pitches, 3 rugby pitches, a white water canoe and kayak course on the Ariege river, which has hosted international junior kayak competitions, a 250m velodrome, and 4 open-air and 2 covered tennis courts.

Across the athletics stadium car park there is a martial arts centre, the Dojo de Foix.

Hosting History: The botanical garden, Les Épines de Lespinet, has a collection of cacti and succulents, as well as citrus trees, banana plants, and Mediterranean vegetation.

The castle rock is geologically part of Mount Saint Sauveur, to the North West of the town and was separated from it due to erosion by the river Arget.

The round tower is of Gothic architecture with large bays illuminating beautiful hexagonal vaulted halls.

In 1340, the Bishop of Pamiers, Arnaud Villemur, had to intervene against the bad behaviour of some of the increasing numbers of pilgrims (there were reports of noisy evening events).

After the destruction of the city walls, tree planting and urban landscaping works, including a fountain and bandstand, made it a popular venue for promenading by the townspeople.

The plane-tree-lined central reservation of the Allées de Villote contains the town war memorial as well as a car park and is currently a main site for festive occasions and for the Friday market.

The street is lined by shops, cafés and restaurants and public buildings as well as a monument to the resistance to and deportees of the Second World War Nazi occupation.
