[있을 법한데 없는] 지하상가 온실

One long section of an underground shopping arcade in Seoul converted into a walking greenhouse. The original terrazzo floor and the arcade's mirrored support columns are kept, but the shop units on both sides are now planting beds — ferns, rubber plants, small citrus trees — growing right up to the walkway edge. A row of skylights cut into the ceiling drops shafts of pale daylight onto the floor, supplemented by grow lights on the old fluorescent rails. Condensation on the tiled walls. Three elderly people walking slowly for exercise, one with hands behind the back; a woman sitting on a bench reading. The arcade's original directional signage in Hangul is still bolted to the ceiling above the greenery. Damp air, faint mist near the floor. Documentary photograph of a real place in daily use — not abandoned, no peeling paint, no dust. No real company logo, no real brand name.
