The Warner Grand Theatre is a lavish, Art-Deco theatre originally opened to the public on January 20, 1931. Designed by B. Marcus Priteca the Grand Theatre was one of three lavish Art-Deco Palaces located in San Pedro, and the other two in Beverly Hills.

Jack Warner called it "The Castle of Your Dreams." The Warner Grand Theatre was designed by architect B. Marcus Priteca and interior designer A.T. Heinsbergen. Mr. Priteca designed three lavish art-deco palaces which were located in San Pedro, Beverly Hills, and Huntington Park. The Warner Grand is the last of the three original theaters left intact and has been undergoing gradual refurbishment after a thirty-year decline. Priteca later designed Hollywood's famous Pantages Theater.
