The Castle of Graines is a castle in Val d'Ayas, located near the village with the same name in the municipality of Brusson
, Aosta Valley
, northern Italy
It occupies the summit of a rocky spur which commands Brusson and most of the Val d'Ayas. In medieval times, it communicated through flag or mirror messages with the nearby Tower of Bonot and the Castle of Villa at Challand-Saint-Victor
According to a legend, a large treasure lies buried under the castle.
The castle had the typical layout of Aosta
Valley early medieval castles. It had an irregular line of walls measuring c. 80 x 50 m, which housed a series of structures such as the large donjon (square tower) and a small chapel, the only ones remaining now.
The donjon is square in plan, with a side of more than 5.5 meters. It was the castle's keep and the residence of the castellan or the lord. The entrance was at some five meters from the ground, and could be accessed only through a ladder which could be removed during sieges. A wing was later added to enlarge the tower.
The Romanesque chapel, dedicated to St. Martin, has a single nave with a length of eight meters, ending in a semicircular apse. The ceiling had crumbled down.
