In the middle of the Middle Ages, while tried to develop in the plain of “Borough-Argental” (Burgus Argentalis), the lords of the area had prudently installed their castle with the variation, with the Argental locality.
This name of Argental, which is also that of the brook, could refer to mines of money, appears it present in the area, as it is of siver-bearing lead on the side of St-Julien-Molin-Serrated roller, Eteize or elsewhere in Pilat.
The most former known lords, attested starting from XII century, had name Pagan of Argental, with title of barons.
The construction of the castle goes back at least to this time. The old engravings show it provided from a high keep and protected by an enclosure and turns. You can suppose that it supervised a road and sheltered a garrison.
The centuries then passed and the Pagan heiresses married with of Retourtour, Tournon, Josserand, of Monchetun, De Brion and Of Bourbon, while the territory oscillated between Vivarais and Forez.
The wars of religion, violent in Vivarais, were right of the castle. Still occupied in 1594 by Members of a league a little too insolents, the royal capacity made it capitulate and ordered its demolition in 1595. Its higher walls, however “thick and cemented well” were dismantled.
The vault was preserved, just as some sections of wall and the pretty base of a turret. All these elements remain still visible. The vault in spite of was very altered thereafter and, when it is open, it offers a pleasant volume and various disparate elements.
