Fort Saint-Jean is a historic fortress located at the entrance of the Old Port in Marseille, France. Constructed by King Louis XIV in 1660, the fortification was built on the site of earlier military structures dating back to the 12th century used by the Knights Hospitaller. The fort played a critical role in the defense of the city and has intersected with many noteworthy events in French history, from the French Revolution to the Second World War. Enclosed by high walls and featuring distinctive round towers, Fort Saint-Jean connects to the newer addition of the Museum of European and Mediterranean Civilisations (MuCEM) by a sleek, modern footbridge. After an extensive renovation in the 21st century, it has become a cultural hub, offering visitors a chance to dive into the rich maritime history of Marseille while enjoying panoramic views of the sea and the city. The site includes beautiful gardens, offering a peaceful retreat from the urban hustle.
