and to think you can only see about 1/4 of the highrises on this picture...
the place where the two red dots almost connect is the place from where the panorama was taken: the north tower of the CENU Complex.
Then you can see the panorama angle. Notice that you can only see HALF the city in the direction of the pictures, because the Paulista Avenue is on a hill, and with the added height of the towers over it, it blocks the view to the other side of the city, where the old downtown, and some of São Paulo tallest buildings, like Italia, Copan, Banespa, etc, are located.
some bonus pictures
this is the CENU complex, and the middle tower, the higher one, is the North Tower, from where the panorama pics were taken.
