The site received a major re-landscaping at the beginning of the 16th century, during the pontificate of Pope Julius II. Donato Bramante's original design was then split into three new courtyards, the Cortili del Belvedere, the "della Biblioteca" and the "della Pigna" (or Pine Cone) in the Renaissance landscape design style. Also in Renaissance style, a great rectangular Labyrinth, formal in design, set in boxwood and framed with Italian stone pines, (Pinus pinea) and cedars of Lebanon, (Cedrus libani). In place of Nicholas III's enclosure, Bramante built a great rectilinear defensive wall.
