Listed in the Inventaire Supplémentaire des Monuments Historiques, this fort originally consisted of a gun tower rising over 2 vaulted levels. It is characterized by its 5-pointed star-shaped enclosure.
Following the British occupation in 1793, part of the tower was destroyed. Under the Empire, the missing part was rebuilt on a square plan.
First declassified in 1885, the fort lost its military function when it became the property of the Parc national de Port-Cros in 1997.
Its position overlooking the north of the island offers a remarkable panorama of the Hyères roadstead.
