Saint-Rémy-de-Blot (French pronunciation: [sɛ̃ ʁemi də blo]; Auvergnat: Sent Remesi de Blòt) is a commune in the Puy-de-Dôme department in Auvergne in central France.

Château Rocher (originally called "Blot-le-Château") is situated on a 150-meter cliff overlooking the Sioule.

Its objective was to monitor the Sioule valley and the Menat bridge, a crossroads between Auvergne and Bourbonnais.

The fortress was built at the end of the 11th century at the initiative of Archambaud the Fort, lord of Bourbon.

In July and August, the Château-Rocher Association offers guided tours.
