Consider the Stuart Collection a work in progress on a large scale. Through a 1982 agreement between the Stuart Foundation and UCSD, the still-growing collection consists of site-related sculptures by leading contemporary artists. Start by picking up a map from the information booth, and wend your way through the 1,200-acre campus to discover the 14 highly diverse artworks. Among them is Niki de Saint-Phalle's Sun God, a jubilant 14-foot-high fiberglass bird on a 15-foot concrete base. Nicknamed "Big Bird," it's been made an unofficial mascot by the students, who use it as the centerpiece of their annual celebration, the Sun God Festival. Also in the collection are Alexis Smith's Snake Path, a 560-foot-long slate-tile pathway that winds up the hill from the Engineering Mall to the east terrace of the spectacular Geisel Library (breathtaking architecture that's a fabulous sculpture itself); and Terry Allen's Trees, three eucalyptus trees encased in lead. One tree emits songs, and another poems and stories, while the third stands silent in a grove of trees the students call "The Enchanted Forest." Allow at least 2 hours to tour the entire collection.
