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! 🍪🔥

⚓ Short info about the yacht • Year of construction: 1901 in Germany (originally as the training ship „Großherzogin Elisabeth“) • Use: Training ship for the merchant navy • After the Second World War handed over to France • Today: Museum ship & landmark of Dunkerque Old soul, calm harbor In the middle of the port of Dunkerque lies the Duchesse Anne – a piece of history from another time. Over 100 years old, once sailing the world's oceans, today firmly moored – and yet you can feel the spirit of wind, salt, and freedom in every mast. A moment to pause… before the real headwind awaits outside again 🌬️
