Isle of Aix (île d'Aix), in the Atlantic Ocean. It is a popular place for tourist day-trips during the summer months. Napoleon famously visited the island in 1808 and gave directions to reinforce the fortifications. He ordered the construction of a house for the commander of the stronghold (today's Musée Napoléon) and the construction of Fort Liedot, named after a colonel killed in the Russian campaign.
In 1809, the Battle of the Basque Roads was a naval battle off the island of Aix between the Royal Navy and the Atlantic Fleet of the French Navy. On the night of 11 April 1809, Captain Thomas Cochrane led a British fireship attack against a squadron of French warships anchored in the Basque Roads. In the attack, all but two of the French ships were driven ashore. The subsequent engagement lasted three days but failed to completely destroy the French fleet.
From 12 to 15 July 1815, Napoleon also spent his last days in France at Île d'Aix, after the defeat at Waterloo, in an attempt to slip past a Royal Navy blockade and escape to North America. Realising the impossibility of accomplishing his plan, he wrote a letter to the British regent and finally surrendered to HMS Bellerophon, which took him to Torbay and Plymouth before he was transferred to Saint Helena.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
