Origin and history

Fort Liedot, originally named fort of the Summity, was ordained by Napoleon I in 1808 to defend the island of Aix against enemy landings. Built between 1810 and 1834 under the direction of engineer Thuillier, this 90-metre square fort, with four bastions, uses stones transported from the quarries of Crazannes. Semi-entered to resist artillery fire, he embodied the expertise of military engineering officers. Renamed in 1812 in tribute to Colonel Liédot, who died during the Russian campaign, he is the only copy of model dread No. 1.

Although designed for defence, the fort never underwent a real attack, except for French training shots in 1863. It was mainly used as a prison: first for political prisoners after the Paris Commune in 1871, then for Russian mutineers in 1917 (including 249 soldiers, some of whom died of the Spanish flu). Between 1959 and 1961 he held Ahmed Ben Bella and his FLN companions under high military supervision. These years marked the island, divided and militarized.

After World War II, the fort became a vacation colony managed by the Ministry of the Army (1948–1958, then 1962–1980). Left behind, it was bought in 1989 by the Conservatoire du littoral, which undertook its rehabilitation. Ranked a historic monument in 1995, it is now open to visitors, attracting hikers and cyclists. Its unique architecture and its turbulent history make it a major testimony to the French military heritage.

The fort is part of a defence of the mouth of the Charente and the Rochefort arsenal. Its structure, protected by 380 metres of land, illustrates the strategic innovations of the 19th century. The late modifications (1878–80, 1889) strengthened his role as a reducer in a cut-off camp. The stones, transported by river from Saint-Savinien, underline the logistical effort of the time.

His famous detainees include Communards, leaders of the Russian mutiny in La Courtine (1917), and Ahmed Ben Bella, future Algerian president. These episodes reflect the political and colonial tensions of France in the 19th and 20th centuries. The fort, public property, remains a symbol of the changes in its use, from repression to heritage preservation.
