Château de Peyrelade Rivière-sur-Tarn, Aveyron, France. A castle existed here at least as far back as the 12th century. It was the scene of incessant battles and sieges until 1633 when it was dismantled on the orders of Cardinal Richelieu. Thanks to its position controlling the entrance to the Gorges du Tarn, it was one of the most important castles in the Rouergue province. The name is derived from the occitan "Pèira Lada", meaning wide rock.
