SCP-173 is a reinforced concrete sculpture of unknown origin measuring 2.0 meters tall and weighing approximately 468 kg. The statue is vaguely humanoid in shape, although improperly proportioned. Traces of ketchup brand spray paint on the statue's upper body, resembling a face. SCP-173 consists of multiple individual concrete portions joined by steel reinforcing bars. The two appendages projecting from the upper section of the sculpture consist of exposed and tangled reinforcing bars where the concrete has disintegrated.
