Located on the edge of an ancient alpine pasture, the Chapel of Sts. Andrew and James of Horres in Millaures probably dates back to the late 15th century, and is fully decorated, both outside and inside, by pictorial cycles created by three distinct fresco painters who worked simultaneously around the 1630s. On the exterior is a striking Cavalcade of Vices and Virtues, unfortunately partly mutilated, overlaid with a depiction of Saints Peter and Andrew. In the scene of the cavalcade, the individual vices are personified by men and women placed astride symbolic animals and tied around their necks by a chain, who are pushed by a host of devils toward the mouth of Leviathan, located on the left. The interior, embellished with a beautiful wooden chancel, is almost fully decorated. The chancel area houses scenes from the life of St. Andrew the Apostle, as well as depictions of an elegant St. Lucy and a fragmentary St. Anthony of Padua, while the vaults of the prayer hall feature scenes from the life and martyrdom of St. James, flanked by depictions of the Mass of St. Gregory and St. George slaying the dragon.
