The castle of Riau, a listed building, dates from the XV, XVI and XVIII centuries.
As evidenced by the terriers kept in the castle since 1308 the lordship of Riau has already, in the early fourteenth century, an important place in the history of Bourbonnais.
All rare and typical architecture of Bourbon fifteenth and sixteenth centuries, the Riau, built on a motte, surrounded by a moat whitewater. Access to the courtyard of the castle by an imposing entrance tower flanked by two turrets. Outside the enclosure stands a most remarkable and most unusual tithe barn that can be seen today in France. In the fifteenth, Charles Popillon, grand treasurer of Anne of France, and his descendants improve the castle for three centuries. The family of Admiral Antoine de Charry Drops succeeded them in the eighteenth century. In 1826 Jean Rene Le Roy de Chevigny, then prefect of the Alliern bought it. His descendants still live here today.
Lounges and furnished apartments in the eighteenth and Empire. Fine collection of paintings by Emmanuel de La Villéon, post-impressionist painter. Permanent exhibition of miniature furniture.
