After Lille fell to the French, Vauban imporved the town's fortifications. He created a powerful pentagonal citadel to the north of the town. In addition to this, he also strengthened the urban defences, resulting in a trace of 16 bastions and 4 hornworks. |
There was also a fort, called Fort Saint-Sauveur, that was self-contained but formed a bastion in the defences. Today only the citadel and Roubaix, Ghent and Paris gates survive, but even these remains are very much worth a visit. |
