The d'avis family built this fortress beside the Roman road of Gaul that ran through the Runaz territory from East to West. Towards the end of the 15th century the d'avis signoria was divided among four brothers: Jean l'ancien touched Valgrisenche, Boniface touched Avise, Rolet dominated on Leverogne and Planaval, and finally Jean le Jeune was Lord of Runaz. Probably he was to transform the fortress into a dwelling: proof of this beautiful Windows dating from the 16TH century. The style is late Gothic and the cornice is in Villeneuve stone. Interesting entrance.
The parish Museum preserves some interesting sacred objects, including a crucifix dating back to the second half of the 13th century and two reliefs of German manufacture representatives St. Rocco and St. Sebastian, attributed to the workshop of the sculptor Michael Parth, active from Friuli Tyrol during the second half of the 16th century.
