The Fort Saint Jean is a military complex that has a lot of history in Marseille. Although the foundations date back to the late 12th century, the fort was built on the site of Saint John of Jerusalem base in the 17th century, when Louis XIV decided to reinforce the city’s defenses. It functioned as a military building for more than three centuries. During the Second World War, it was used by the Germans as military storage and was seriously damaged by an accidental explosion in 1944. We were able to climb one of the towers and walk along the front of the fort. It's about a minutes walk from our apartment and we've already walk in and around it just because we like it so much.
