The new UCLA campus in 1929 had four buildings: Royce Hall and Haines Hall on the north, and Powell Library and Kinsey Hall (now called Renee And David Kaplan Hall) on the south. The Janss Steps were the original 87-step entrance to the university that lead to the quad of these four buildings. Today, the campus includes 163 buildings across 419 acres (1.7 km2) in the western part of Los Angeles, north of the Westwood shopping district and just south of Sunset Boulevard. In terms of acreage, it is the second-smallest of the ten UC campuses. The campus is approximately 1 mile east of I-405 (the San Diego Freeway).
