The history of Fort Saint-Jean
Situated at the entrance to the Old Port, on the north bank, Fort Saint-Jean is one of Marseille’s most iconic historic monuments. Overlooking the harbour entrance, it forms part of a military complex closely linked to the city’s history. Originally, the site was home to the Commandery of the Knights Hospitaller of Saint John, which served as a staging post for the Crusaders on their way to Jerusalem from the 12th century onwards. Completed in 1365, this complex comprised a chapel, a church, a hospital and a palace.
In the 15th century, King René had an imposing square tower built between 1447 and 1453 to strengthen the defences of the port of Marseille. The famous round tower, now the fort’s iconic feature, was built in the mid-17th century.
In 1664, shipowners proposed further fortifying the site by adding a watchtower, visible up to 20 kilometres out to sea, to facilitate the arrival of merchant ships. A few years later, on the orders of Louis XIV, Fort Saint-Jean was built between 1668 and 1671 following the expulsion of the Knights Hospitaller.
Following a revolt by the people of Marseille, the engineer and architect Vauban had a moat dug to isolate the fort from the rest of the city. The site retained its military function until the French Revolution, when it was converted into a state prison. During the Second World War, whilst being used as an ammunition depot by the German army, the fort was severely damaged by an accidental explosion.
Opposite Fort Saint-Nicolas, Fort Saint-Jean is now one of Marseille’s must-see landmarks. Much loved by visitors and locals alike, it offers a remarkable view of the Old Port and the harbour of Marseille. Having become a true cultural hub, the fort regularly hosts exhibitions and audiovisual installations. It is connected by footbridges to the Mucem, the first major national museum dedicated to the civilisations of Europe and the Mediterranean, as well as toSaint-Laurent Church, forming a unique heritage complex in the heart of Marseille.
