London introduced its new architectural symbol today, a 115-meter (377-foot) observation tower known as the ArcelorMittal Orbit, or "Orbit" for short.

Like many of its predecessors around the world, its aim is to serve as a symbol of civic pride for the city and for the urban regeneration of its neighborhood.
