The Nations Wall is a monumental sculpture made of tubular steel, 261 m long (856 ft), which stands just south of the Plaza of the Nations and the central axis. Designed so that it can move mechanically in a wavelike motion, the sculpture is made up of 960 vertical elements, each 20 m tall (66 ft), which are operated by 480 motors. The Wall’s function, in part, is to create an architectural screen for a large hall that stands to the south, so that this building may be visually integrated with the complex. In motion, the Nations Wall will create a pleasing effect of light and shadow over the central axis and Plaza of the Nations. It can be adapted to serve as a giant projection screen for events held in the Plaza of the Nations.
