The image depicts the Écluse Saint-Pierre (Saint-Pierre Lock) on the Canal de Brienne in Toulouse, France, at night. The scene is illuminated by artificial streetlights and the bright, nearly full moon positioned high in a dark, cloudless sky. In the foreground, a set of worn, light-colored stone steps descends from the left, leading to a cobblestone platform adjacent to the canal lock. Scattered debris, possibly small rocks or mortar fragments, is visible on the lower steps. To the right, another set of stone steps ascends towards the right edge of the frame. The lock itself features walls constructed from reddish-brown brick and lighter stone blocks, with dark water visible at the bottom. The large, closed lock gates, positioned centrally, display circular structural details. A metal winding mechanism (capstan) is present on the cobblestone platform to the left of the lock. Black wrought-iron railings line the edges of the lock platforms and steps. Above the lock, an arched bridge, also constructed of reddish-brown brick, spans the canal. A small, dark, rectangular building or control booth is situated on a platform near the arch. In the midground and background, a higher-level promenade or road runs horizontally across the frame, lined with mature deciduous trees displaying yellowish-green foliage. Several modern streetlights illuminate this upper level. Indistinct human figures are visible on the promenade, some appearing to be seated or gathered in small groups, while one figure is near a bicycle parked on the far right. Beyond the treeline, a dark body of water, likely the Garonne River, is visible in the far distance.
