Fort-la-Latte or Castle of La Latte was built on a small piece of land at the Baie de la Fresnaye in the 14th century. In 1379 it was conquered by Bertrand du Guesclin. It was besieged by the English in 1490 and by the holy League in 1597. Garangeau under the reign of Louis XIV turned the castle into a fortress, using Vauban's building plans. They used canon batteries, stationed in Fort La Latte, to defend Saint-Malo against English and Dutch attacks. In the year 1793, a melting furnace for cannon balls was built and some counter-revolutionary suspects were imprisoned at Fort la Latte. The last attack happened in 1815 during the Hundred Days (French Cent-Jours) (also known as the Waterloo Campaign, it describes Napoleons return to power between 20 March 1815 to 28 June 1815), when a few men from Saint-Malo unsuccessfully attacked the castle.
Various films have been shot at this site. Today Fort-la-Latte is a famous tourist attraction.
References:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
