The French king heaped titles on Duke Anne of Joyeuse caslte in Couiza, near Rennes le Chateau; Mt St Michel governor; Grand Admiral of France; wedlock to the king’s sister in law, a Mercœur. As Protestant civil violence subsided, Anne repaired Joyeuse. He killed 800 Huguenots in Poitou, the St Eloi massacre of 21 June 1587, a rash duty. He led the army against Huguenots and the king’s arch enemy, Henry of Navarre, but was taken near Bordeaux. Joyeuse palace had a varied history, and became part of the grail romances.
