In Guilers, a manor house is causing a stir. Built in the 16th century, it was for a long time the property of the Penancoët family, Counts of Kerouazle.
In 1649, the manor was home to Louise Penancoët de Keroual, a young noblewoman whose destiny was far from ordinary. She became maid of honour to Henriette of England, the Duchess of Orleans, sister-in-law of Louis XIV and sister of the King of England. Louise Penancoët de Keroual had a very good reputation. Cultured, she was noticed by Charles II after a diplomatic visit. A year later, the young Breton became Charles II's mistress and remained faithful to him until his death.
