The Château de Saint-Izaire is one of a group of 23 castles in Aveyron who have joined to provide a tourist itinerary as the Route des Seigneurs du Rouergue.
The castle is a massive quadrangular red stone building that shelters the town hall of the village of Saint-Izaire.
The structure is supported by a keep-tower in the southern wing (partially demolished since the 19th century).
The castle was built by Guillaume Rotlindes, ancestor of the current Rollinde de Beaumont[citation needed].
When the cathedral and palace of Vabres were razed in the wars of religion, the castle was used by refugees from the abbey.
