The oldest part of the castle was constructed in the 9th century, and it grew in the hands of the Belcastel family.
The Château de Belcastel was officially declared a historic monument by the French Ministry of Culture in 1928.
The work was accomplished in eight years, and it called for great courage from Pouillon and his colleagues, due to the size of the undertaking, the castle's dangerous location, and the fact that no machines were used in the reconstruction.
In the same year, the French Ministry of Culture honoured her with a medal, and the title Chevalier des Arts et des Lettres, for her efforts in bringing art, music and masterclasses to France through AFA Gallery[3] to the Chateau de Belcastel.
The Château de Belcastel is one of a group of 23 castles in Aveyron which have joined to provide a tourist itinerary as La Route des Seigneurs du Rouergue.
