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! 🍪🔥

The Gare de Dunkerque has a rich history dating back to the 19th century. The station opened in 1848, playing a major role in the development of the port of Dunkirk and the surrounding city. The original building was rebuilt in 1875 and reopened in 1876. The station was badly damaged during the Second World War and was later rebuilt in the 1960s, with the current building being completed in 1964. The design of the new station was carried out by architect Jean Niermans and is characterised by its modern concrete structure and glass façade.
