Riom
Riom grew around the church and relics of Saint Amable, a centre of pilgrimage in the Auvergne. It became the capital of the ducal lands of Auvergne, and the patronage of Duke Jean of Berry gave it a ducal palace and a Sainte-Chapelle. The Bourbon family held the duchy from 1416 until 1527. Riom and the duchy subsequently passed to Louise of Savoy and were joined definitively to the French crown in 1531.
