History
The center opened on 10 February 1964, anchored by a three-level May Company and a two-level Montgomery Ward, with 83 retailers across two levels — the first fully enclosed, climate-controlled regional mall in Southern California. The Broadway joined that August, dedicated as a third anchor.
What follows is a narrative spine, hung on the major events in the record, and beneath it the complete chronology — the center itself, and the surrounding retail context that shaped it. Each entry links to its own page, where the sources and photographs sit. Major turning points are marked; this page is edited prose over generated data.
