From a promontory on the south slope of 1,625ft Mt. Hollywood, Griffith Park's highest peak, this Art Deco observatory (1935) was donated by Col. Griffith at a cost of $255,780. With its central 84ft copper planetarium dome and two smaller flanking domes, the observatory is one of Los Angeles' most distinctive landmarks. After a four-year, $93 million restoration and expansion, it reopened in November 2006 to widespread acclaim. Some 40,000sq ft of public space, a 200-seat theater, a café and bookstore have been added, and the planetarium has been equipped with state-of-the-art technology. It is now one of the city's premier family destinations.
