Allow me to introduce: Jean Bart, arguably the coolest corsair (or pirate!) France ever had! 🏴☠️⚓️ He saved the country from hunger and is today the soul of Dunkirk. The fact that this statue survived World War II almost unscathed makes it sacred to the locals. An absolute must-see when you're here – and don't forget to eat a 'Jean Bart Finger' pastry afterwards! 🍪🔥
