The Château de Montaigut is a castle in the French commune of Gissac in the département of Aveyron.
[1] Built on a rocky outcrop dominating the valley of the Dourdou de Camarès river, it defended the town of Saint-Affrique against attacks from the south.
Enlarged and transformed in the 15th century by the Blanc family, it was restored several times before falling into ruin.
[2] The association Amis du château de Montaigut, which took ownership in 1968, undertook a massive restoration.
It is one of a group of 23 castles in Aveyron which have joined together to provide a tourist itinerary as the Route des Seigneurs du Rouergue.
