The museum, in a convent that belonged to the Urbanistes Sisters, recounts the evolution of Lille from the year 1000 to 1835. It holds a collection of three thousand objects, some of them linked to the Confrérie de Sainte-Barbe whose members swore an oath in 1483 to defend the city and to train regularly for this purpose. Even though this brotherhood was later dissolved, the Cannoniers showed remarkable courage during the Austrian siege of 1792. In recognition of their resistance, Napoleon Bonaparte gave them two Gribeauval canons, which you can still see today, exhibited in the museum. You'll also find 16th-century maps of the county of Flanders, all kinds of rifles made between 1777 and 1945 and bayonets.
