It was built in the Fort Boyard

A bit of history: in 1666, Colbert, French Finance Minister under Louis XIV, ordered the established shipyards to build ships near the town of Rochefort, at the mouth of the Charente river.

The Fort, built in the middle of the Strait, together with the shore batteries might block the passage to the shipyards, creating in front of the enemy ships "fire barrier".

However, the legendary engineer-fortifier Sebastian Le Prêtre de Vauban, to whom Louis XIV had offered to lead the construction, refused, protest the king: "Sire, it is easier to grasp the moon teeth than to build a fortress in this place."

The idea of Fort building back in the early nineteenth century. By the time construction technology has allowed the building of such a fortress, and the need was very urgent foreign policy of Napoleon I strongly complicate the relations of France with Britain.

The construction of the Fort was begun in 1801, already existed in the Strait sandbank, from the name which was the name of the Fort.

During the construction of the foundations of the Fort the stone blocks were installed directly on the seabed. Soon, the builders are faced with serious technical difficulties — blocks of stone went into the ground under its own weight, warp and went home.

As a result, in 1809, the construction of the fortress was suspended and only resumed in 1837, during the reign of Louis-Philippe I, when relations with Britain were again very intense.

The construction of the Fort was "protracted" — the fortress was completed until 1857. The final structure was a very impressive Fort had a length of 68 meters and a width of 31 meters and a height of walls up to 20 meters.

Garrison Bayar consisted of 250 people. However, by the time of completion of construction of the Fort was that the fortress in General is no longer needed. For more than 50 years since the laying of the Fort, the artillery range has increased dramatically, and now coastal batteries easily blocked the Strait.

Thus, the need for newly built Fort has disappeared, but he left in charge of the Military Department of France and subsequently was used as a prison, not participating in the hostilities.
