Boulogne's Basse Ville (Lower Town) is dominated by its fishing port . Hungry seagulls dive and squawk overhead as they survey the fishing boats and the poissonniers (fishmongers) selling freshly landed cabillaud (Atlantic cod), carrelet (plaice) and sole – Boulogne's most important commercial fish – as well as bar (sea bass), mullet, raie (skate) and turbot. Take a good look so you know what you're getting next time you order poisson (fish).
