The Maison des Consuls of Mirepoix dates from the 13th century. On January 5, 1274, Guy III of Lévis granted the city's inhabitants the right to elect consuls. After a massive flood in 1289, he granted the population a significant concession of land on the left bank of the river to build a new town. Consuls received the right to erect their dwellings, and they bought a house destined to become a town hall serving as a tribunal, council chamber, and prison. Its facade beam is a heart of oak nearly 39 ft (12 m) long and more than 24 in (60 cm) thick. No less than 104 sculptures adorn the ends of the springers, the beams perpendicular to the facade, and the supporting pillars.
