Balaguier Museum is a unique maritime museum housed within the walls of an old fort on the shores of the picturesque roadstead of Toulon. Located in France, this site attracts history buffs and adventure seekers with its authentic atmosphere and imposing 17th-century architecture.

The museum building is a massive circular tower, erected between 1634 and 1636. Originally, the fort served as a vital defensive outpost to protect the coast from Spanish fleet invasions. Walls nearly four meters thick hold the memory of past battles and the strategic importance of this region.
Today, the museum's exhibits are dedicated not only to military history but also to the fascinating underwater world of the Mediterranean. Visitors can learn about the history of the Toulon penal colony and the lives of prisoners, as well as immerse themselves in modern exhibitions that reveal the secrets of the deep sea using the latest technology.
