Boulogne-sur-Mer, in the Hauts-de-France region, is a dynamic port city and the heart of French fishing. Its identity is split between the upper town (Ville Haute), with its medieval ramparts, UNESCO World Heritage belfry, and 13th-century castle housing a museum with Egyptian and Greek collections, and the lower town (Ville Basse), centered around the bustling port and Nausicaá. This spectacular aquarium offers an immersive journey through the world's oceans, making it an unmissable attraction. The city also played a crucial role in history, from Roman times to the Napoleonic Wars, leaving a palpable legacy in its architecture and traditions.
For a complete experience in Boulogne-sur-Mer, dedicate time to both the Ville Haute, strolling along its ramparts and visiting the castle-museum and basilica, and the Ville Basse. Here, Nausicaá is the star, but don't miss the atmosphere of the fishing port. The best time to visit is from spring to autumn for pleasant weather. Getting around the city is easy on foot, especially in the center. For an unforgettable adventure, try the port restaurants serving the catch of the day.
