The image depicts the interior of the Cathédrale Notre-Dame-de-la-Treille in Lille, France. The scene is dimly lit, showcasing the cathedral's main altar area. In the background, a large, multi-panel stained glass window, predominantly blue, red, and yellow, features detailed religious depictions, including a central crucifixion scene. Below this window stands an ornate, golden-colored neo-Gothic reredos, intricately carved with numerous spires and housing multiple white sculpted figures arranged in scenes, possibly depicting biblical narratives. To the left, a large, dark wooden pulpit with carved relief panels is partially visible. Tall stone pillars are positioned on both the left and right sides of the central altar area. In the lower midground, a gathering of approximately 20-30 individuals, mostly adults, stands facing towards the altar, observed primarily from behind or in profile. One individual in the far right mid-ground appears to be wearing a dark robe. A floral arrangement in warm tones of red, orange, and yellow is situated on a low stand in the lower right foreground. The environment is a grand ecclesiastical space, with localized lighting illuminating the altar and stained glass against the general dimness of the cathedral interior.
