I’ve been photographing the World Health Organization building in black and white, regularly, because the architecture lends itself so very nicely to geometric abstracts. Here it is in color, to show a different take on photo abstraction and the creation of meaning in an image.

The building itself was designed by Uruguayan architect Roman Fresnedo Siri. In 1961, Siri won an international design competition with his arc and cylinder concept. Construction was begun in 1963 and the building opened officially on September 27, 1965. There are bronze plaques on the face of the tower representing each of the 29 member nations.
