The image depicts the Flag Tower of Hanoi (Cột cờ Hà Nội) within the Imperial Citadel of Thăng Long, Hà Nội, Vietnam, at night. The central subject is the stone and brick tower, which rises from a multi-tiered square base. A solid red flag flies from a flagpole at the apex of the cylindrical tower. The tower's cylindrical section is illuminated with a red wash and prominently features a large, bright green hammer and sickle symbol projected onto its surface. The square base below the tower is also illuminated with warm yellow spotlights highlighting its architectural details and multiple arched entrances. White LED strip lighting runs along the top edges of the railings on the base's upper tiers, and an arched entryway lower down is bathed in blue light. The sky above is dark gray, indicating nighttime conditions. Foliage from trees is visible on the far left. The foreground features blurry, out-of-focus elements: a rectangular, reddish object on the left and a vertical, blue and white object on the right, framing the illuminated tower. No individuals or specific actions are discernible.
