beside it are historical monuments. The mine was opened at the start of the 19th century. Around 1850 the system for workers to descend was modernized using a mechanism housed in the tower. The bathhouse with a hot pool for miners was the first in the Saint Etienne basin. The headframe of the Combélibert mine was originally located on rue Michelet but was moved to the Gourd-Marin site and registered as a historical monument. It is probably the only wooden headframe from the 19th century preserved in Europe. Private houses The Château du Mouillon has a central part that corresponds to the original house and dates back to the 18th century. The complex was acquired in 1850 and developed successively by two families of industrialists. First Lucien Arbel, then in 1894 by Jean-Marie Marrel and his son Henri, who had it improved by Parisian designers and artisans. The building, common, garden and some rooms (entrance hall, staircase, old dining room to the north, large oval salon to the south, woodwork and decor of the old library on the ground floor, wood fireplace first floor) are included in the inventory of historical monuments. The house of the Men of Stone (La maison des Hommes de pierre) was built between 1880 and 1883 by Charles and Étienne Marrel near the first plant of the Marrel Brothers company. The main façade is distinguished by its stone balconies decorated with ironwork, carved window lintels and two towering statues of 'men of stone" supporting the balcony of the first floor. To the west is the blacksmith with his leather apron, to the east metallurgy is represented by the tongs. The ground floor is occupied by three interconnecting reception rooms that open onto a hallway decorated with wood paneling decorated in faux marble with a mosaic floor. To the left after the entry there is a small living room decorated with a white fireplace in Louis XV style. The blue ceiling is decorated with trompe l'oeil roses. Two double doors lead to the "Grand Salon" with ornate woodwork and a black fireplace, a painted ceiling with a plaster rosette.
