A 1677 map, still using the Dutch name of Bourg Louis, shows a watchtower, some small batteries and a miniature star-shaped fort on  Morne Cépérou.

A report that year says the small (peu spacieux) fort had walls that were so thin they were disintegrating.

In 1689 new fortifications for the town were laid out by Sébastien Le Prestre de Vauban, the king's engineer.

Vauban's fortifications were built between 1689 and 1693.

The original Fort Cépérou remained, surrounded by the much more extensive ramparts of Vauban.

In 1701 the structures in the fort were destroyed by a fire that spread to the palm-thatched huts of the city.

The Portuguese occupied Guiana from 1809 to 1817 and destroyed all the defenses of Cayenne Island.

The remains of the town's walls were torn down, the fort's bastions were destroyed, and only three dilapidated buildings remained of the fort.

In 1862 governor Louis-Marie-François Tardy de Montravel had a lighthouse built on Mount Cépérou.

By 1864 the fort was almost abandoned.

A great fire destroyed the southeast part of Cayenne in August 1888.

The bell on the fort's pagoda rang for eight days during the fire until it split on 12 August 1888.

A public clock was installed on the site in the first half of the 20th century.

Some walls and a bell tower are all that remain.

The pagoda holding the bell is classified as a monument historique.

In 2016 work was done to rehabilitate the pagoda, which was in danger of collapse.

The site was transferred from the armed forces to the city of Cayenne in February 2009.
