grand, ornate staircase inside a covered passage

grand, ornate staircase inside a covered passage. The staircase is made of dark metal with intricate carvings on each riser, and it ascends towards a brightly lit upper level. Several people are visible on the stairs, walking in both directions. On the left side, a woman in a long light-colored coat is descending, while a woman in a dark jacket is also descending on the right. Further up the stairs, a group of people are walking upwards, including a man in a purple jacket, a man in a white sweatshirt, and two women. The architectural style suggests a historic building, likely a shopping arcade or a grand public building. This scene is located within the Passage Pommeraye in Nantes, France, a renowned 19th-century shopping arcade.
