An undulating circular wall measuring 400 feet in length (with varying heights from 4 to 9 feet) surrounds the garden. Monumental sculpted, playful serpents, decorated in colorfully patterned mosaics, slither along the top of the wall. Their curved bodies form a pattern of solids and voids that allows visitors to see landscape vistas beyond the garden. The "snake wall" has one entrance into the garden. It opens into a maze whose walls and floors are covered with bold patterns of black, white and mirrored tiles. This gateway "announces that you are crossing a threshold into a magical world - the world of your past, your roots, your land, your unconscious dreams", observed Marcelo Zitelli, the artist's curator and longtime assistant. Once through the maze visitors enter the central Courtyard.
