Building of Chambre de Commerce et d'industrie in the center of Lille. The Belfry in front is 76-meters tall.
Night lighting of the building is very well done - color of lights changes every few minutes between red, orange, blue and magenta. It's probably the most frequently photographed place in Lille. I went there 3 times just after sunset, and every time there were at least few people with cameras and tripods taking photos of Chambre de Commerce from the same spot.
