The image displays a nighttime view along the Douro River in Lordelo do Ouro e Massarelos, Porto, Portugal. The primary feature is the Ponte da Arrábida (Arrábida Bridge), whose large concrete arch dominates the midground, supporting a multi-lane deck illuminated by a series of evenly spaced streetlights. The sky above the bridge is uniformly black. In the foreground, a single individual is observed from behind, walking left-to-right on a paved riverside promenade, moving away from the viewer. The person wears a dark upper garment and lighter-colored trousers. A low concrete barrier or wall separates the promenade from the dark waters of the Douro River, which occupies the right half of the lower frame. The river's surface reflects the distant city lights from the opposite bank and the bridge's illumination as shimmering vertical streaks. On the far bank, illuminated buildings and structures are visible against the dark horizon.
