The imposing spire and five naves of equal height make this Gothic church, like the Église Sainte-Catherine de Lille, a fine example of Hallekerque architecture.
Its construction took more than 400 years, from the 14th to the 19th-century. It embodies the Hallekerque (or “hall church”) style that reached its height in the late Gothic period.
The interior is adorned with a number of paintings by artists from the city, dating back to the 17th-century. The central chapel is dedicated to Sainte-Barbe, patroness of the Lille artillery men, whose story is recounted in a museum nearby.
