The Château Bayard is a castle in the commune of Pontcharra in the département of Isère (Rhône-Alpes, France), and dominates the valley of Grésivaudan in the Dauphiné Alps.
Château Bayard has been listed as a monument historique by the French Ministry of Culture since 1915.
The castle has housed the Bayard museum since 1975; it presents the life and the myth of Pierre Terrail, seigneur de Bayard, the famous "knight without fear and without reproach", (French: le chevalier sans peur et sans reproche).
Originally, the Château Bayard was just a fortified manor house. In the feudal age, only a Lord could own a castle. Pierre Terrail, first of the name (the family is also called LeVieux - "the old") and great-grandfather of the renowned knight, was vice-lord of the lord of Avallon.
It has always been important since the castle has been built and restored, that it stay clean.
Starting in 1404, Pierre Terrail undertook the construction of his residence in a place called Bayard, near Pontcharra. Even if it were only a strong house, the building he made was however far from being negligible: illustrations of the 19th century show a residence protected by four round towers, raised on three levels of mullioned windows.
The terrace gives on the valley of Grévisaudan and its marvellous views, opening on vast territories: Jura mountains, those of Vercors plateau, massif of Belledonne and Chartreuse mountains.
