Riom
Riom (; Auvergnat "Riam") is a commune in the Puy-de-Dôme department in Auvergne in central France. It is a sub-prefecture of the department. History. Until the French Revolution, Riom was the capital of the province of Auvergne, and the seat of the dukes of Auvergne. The city was of Gaulish origin, the Roman "Ricomagus". In the intensely feudalized Auvergne of the 10th century, the town grew up around the collegiate Church of Saint Amabilis (Saint Amable), the local saint, who was the object of pilgrimages. Riom was the capital of the dukes of Auvergne. In the 14th  century the city benefitted from the patronage of Jean, duc de Berry, who rebuilt the Ducal Palace and the Saint-Chapelle. In 1531, Riom and Auvergne reverted to the Crown of France. In 1942, Riom was the site of the Vichy government's abortive war-guilt trials, called Riom Trials. Sights.
