Known as the City of Arts and History and also the City of the Sea, Boulogne-sur-Mer enjoys a rich and varied heritage that dates back over 2000 years, and has much to offer its many visitors. Whether it’s the bustling fishermen’s stalls displaying their catch of the day on the harbour front, the beautifully preserved 13th century city walls in the old town, the forest surrounding Boulogne, the dramatic coastline of the Opal Coast, or even the giant aquariums in Nausicaä, the National Sea Centre, there really is something to appeal to everyone.
