The site plan, showing the enclosed elliptical piazza in front of the buildings, with a rising grass mound like the oval pavement at the top of the Capitoline Hill. Walls of changing height surround the piazza, but they stop on the west, at a disappearing-edge pool echoing on a human scale the limitless horizon of the sea, and the cosmos beyond that. Thus the enclosed and the open, the human and the infinite, are brought into contact.
