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.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
