Collegiate Church of Saint-Pierre (Lille)
The Collegiate Church of Saint-Pierre (French: Collégiale Saint-Pierre) was once a large church located in Vieux-Lille, and for almost 750 years it set the pace for Lille's religious life. Seriously damaged during the Austrian siege of 1792, its destruction began in 1794.
