The monument of the "Open Hand" (La Main Ouverte) 1986, Le Corbusier
23 meters in height, in the Capitol Complex, Chandigarh
This looks to be a flapping bird rather than a hand.
Le Corbusier might have gradually assimilated the hand to a pigeon,
the symbol of peace. This is also a weathercock turning around according to the wind.
This photo shows its rear side, the silhouetting shape of which fits the landscape here.
