The family of the rulers of Auvergne (奥弗涅) took possession of the
castle at an unknown date. Guy II of Auvergne owned it from at least
1190.
Whereas Guy II favored the claims of Richard the Lionheart to the
Auvergne, his brother Robert, bishop of Clermont, sided with King
Philip-Augustus (法國卡佩王朝國王 腓力二世·奥古斯都). The tensions between the two
brothers led to the imprisonment of Robert at Tournoël in 1199.
At the end of 1212, the French king sent his army led by Guy of
Dampierre, lord of Bourbon (波旁), who besieged and took the castle. Guy
II lost almost all of his possessions in Auvergne, only keeping the
region around Vic-le-Comte. Philip-Augustus ordered the restitution of
the assets belonging to the Mozac Abbey.
This event — the siege of Tournoël — allowed for the first time the
annexation of the Basse-Auvergne to the crown lands. The territories
seized by the king were called “lands of Auvergne”.
The Château de Tournoël is privately owned and has been listed as a
monument historique by the French Ministry of Culture since 1889.
